What's the youngest a child could develop lung cancer from second hand smoking

What's the youngest a child could develop lung cancer from second hand smoking?
If a child's parents smoked, how long would it take, an approximate minimum, for it to be realistic that the child developed lung cancer because of second hand smoke. (I'm writing a novel and need to know if it is realistic that one of the characters have developed lung cancer from second hand smoking by their parents as a child)

Children do not get lung cancer and second hand smoke is not that big a deal.
3 :
Exactly what the other two posts said. There is no respectable scientific case that relates second hand smoke to lung cancer. The risk is considered NON SIGNIFICANT, because it's exponentially too small to measure, if a link even existed. The 1993 Environmental Protection Agencies linking health concerns to second hand smoke was thrown out by a district judge for cherry-picking their information, even with the bias they could only conclude: â€œThe studies showed that for any given nonsmoker, the lifetime risk of getting lung cancer remains small: 4 to 5 in 1000 ordinarily, and 6 to 7 in 1000 if he or she has been living with a smoking spouse.â€ http://www.gaspforair.org/gasp/gedc/artcl-new.php?ID=40 That's 100% exposure indoors over a lifetime. BMJ did the longest most in depth study and concluded: â€œConclusions The results do not support a causal relation between environmental tobacco smoke and tobacco related mortality, although they do not rule out a small effect. The association between exposure to environmental tobacco smoke and coronary heart disease and lung cancer may be considerably weaker than generally believed.â€ http://www.bmj.com/cgi/content/full/326/7398/1057 The smoke campaigns also like to bring up the idea that it's for the safety of the workers, This shows waitresses in smoke filled bars are exposed to only a 5th of what the EPA considers hazardous: http://www.ornl.gov/info/press_releases/get_press_release.cfm?ReleaseNumber=mr20000203-00 The EPA also states the following: â€œStudies that support a CASUAL association between secondhand smoke and lung cancer.â€ â€œthe chance of declaring these increases statistically significant was small.â€ â€œEPA has never claimed that minimal exposure to secondhand smoke poses a huge individual cancer risk.â€ â€œThe lung cancer risk from secondhand smoke is relatively small compared to the risk from direct smokingâ€ http://www.epa.gov/smokefree/pubs/strsfs.html So as you can see the science behind the health concerns of others over second hand smoke are practically impossible to even been seen in case studies, let along be justification enough to pass any bans. This information needs to be shared with the world, so the lies from the campaigns don't influence people to vote stupidly. Like the quotes goes, "If you hear a lie long enough, eventually it becomes the truth." Also at Forces international they publicly display all the scientific cases done on the matter at: Other Source(s): http://www.washingtonpost.com/wp-dyn/content/article/2007/01/29/AR2007012901158.html http://www.psychologytoday.com/blog/look-it-way/200907/is-second-hand-smoke-really-dangerous http://www.cigarmony.com/downloads/smoking%201440.pdf â€œConclusions: Our results indicate no association between childhood exposure to ETS and lung cancer risk. We did find weak evidence of a doseâ€“response relationship between risk of lung cancer and exposure to spousal and workplace ETS. There was no detectable risk after cessation of exposure.[JNatlCancerInst1998;90:1440â€“50]â€ http://www.gaspforair.org/gasp/gedc/artcl-new.php?ID=40 http://skepticdoc.com/?p=9

my Boyfriends mom has been told she only has 9 monthes to live she has lung cancer and she just started acting very confused or disoriented Is your sister on heavy meds I am almost positive this is the reason , but I will say a prayer for her.
2 :
Thermal lung cancer? I'm not sure I know what you mean by that exactly. Do you mean terminal? Lung cancer frequently doesn't have a lot of symptoms. Maybe a chronic cough, but that is so common, especially among smokers, that it is fairly nonspecific. Unfortunately, by the time more alarming symptoms appear, such as unexplained weight loss, it is because the cancer has already spread and therefore it is too late to really cure. As for your sister being in a daze, it could be because it has spread to the brain. Cancer can also cause you to lose your appetite, so more optimistically, maybe she just isn't getting adequate nutrition. Nutrition drinks like ensure may be worth a try. Good luck and I'm sorry to hear about your sister.

My husband had no symptoms. He thought he hurt his back at work. Was diagnosed March20th passed June 6th. He went thru radiation, chemo, gamma knife procedure(for brain tumor ask your doctor) and took a drug called tarceva. If she is in a daze it could be a tumor on the brain or else the medication. So very sorry for you and your sister. Stay strong and good luck

Can anyone tell me the life expectancy for someone with small cell lung cancer limited stage 3rd level?
My mother was just diagnosed with small cell lung cancer. She has been undergoing testing and just started treatments this week with it. I do know shes at stage 3 and its limited stage. Please any information you could give would be great I have seen some information but hoping what you may find looks better than what i have. We still haven't gotten all the results back yet we will this Friday. But thanks for any and all help.

Small cell is best treated with chemotherapy which aggressively deals with it. If your mother can finish the chemotherapy, then radiation is usually administered. Although each person is different, the five year survival rate is very low. I know that cancer is stressful to the patient and loved ones but try to do your best to help her relax. Plus, it is a good idea that her surroundings are as clean as possible to prevent infection. Her immune system will be compromised. My mother had small cell but was already in a bad shape before she was diagnosed at age 77. Her oncologist was surprised that she didn't respond better to treatment. I can understand what you are going through. I will be thinking of her and sending good thoughts her way. Good luck to you. Please let us know how she is doing.

Stop smoking and start chemo and radiation are the best bets at the moment.
2 :
Without treatment, small cell lung cancer (SCLC) has the most aggressive clinical course of any type of pulmonary tumor, with median survival from diagnosis of only 2 to 4 months. Compared with other cell types of lung cancer, SCLC has a greater tendency to be widely disseminated by the time of diagnosis but is much more responsive to chemotherapy and radiation therapy. Because patients with small cell lung cancer tend to develop distant metastases, localized forms of treatment, such as surgical resection or radiation therapy, rarely produce long-term survival. With incorporation of current chemotherapy regimens into the treatment program, however, survival is unequivocally prolonged, with at least a 4- to 5-fold improvement in median survival compared with patients who are given no therapy. Furthermore, about 10% of the total population of patients remains free of disease during 2 years from the start of therapy, the time period during which most relapses occur. Even these patients, however, are at risk of dying from lung cancer (both small- and non-small cell types). The overall survival at 5 years is 5% to 10%.

Hello Magnolia, I'm sorry to hear about your mom. My husband was diagnosed with cancer over 3 years ago that traveled to his lungs. After going thru chemo and radiation he was no better and the cancer was growing. That's when I found the website http://cancertutor.com.

there's not even DEFINITIVE proof that DIRECT smoking causes lung cancer let alone second hand smoke. especially over such a short period. Fact is, people that NEVER smoked in their lives or were even around secondhand smoke also get lung cancer. It is thought that smoking increases the risk but that's all there is to it. I'm sure your fine. if your experiencing obvious symptoms, see a doctor.

If that was true all four of my dads kids would have lung cancer. He loved to take us for rides in that old station wagon. Then he smoked continually.

It's not 100% positive you'll catch cancer from smoking but it increases your risk at an alarming rate. Tobacco is a carcinogen. And it not only gives you Lung Cancer but also Esophageal cancer, Bladder Cancer, etc.....
2 :
Technically, the only way they could PROVE a causal relationship is by experimenting: that is by having two test groups with randomly chosen participants. One group would be assigned to smoke cigarettes and the other group would have to smoke placebo cigarettes with no carcinogens with neither group knowing if they were smoking for real or not. However, this would be extremely unethical, so it can't be done. But still, there exists such a high correlation between smoking and lung cancer that the causal relationship is assumed by.. well, everyone. Something like 95% of lung cancers occur in smokers or former smokers.
3 :
well, no, not 100% proof. i think it's about the same percentage of proof that stupidity causes dumb questions.
4 :
maybe! But i really think smoking CAN giv u lung cancer! So make sure you don't get into smoking! happy holidays to you too!
5 :
It is not the cigarette but rather the ingredients in the cigarettes such as nitrosamines and benzpyrene. If the ingredients in cigarettes are known cancer causing agents then it is safe to conclude that smoking them can induce cancer.
6 :
I dont think there is any REAL evidence to support the fact that smoking "causes" lung cancer. There are many people who smoke their entire lives and never get lung cancer. And then there are those who never smoked and get it. What we know for sure is that people who do smoke have a higher incidence of all kinds of cancer than those who dont. Everyone has potential cancer cells. I dont know if anyone knows, with certainty, what activates these cells to proliferate into cancer. Since smoking messes with the immune system, the respiratory system along with other systems of the body, it seems to follow that smokers predispose themselves or encourage these cells to grow. The body is not at top function so unable to keep these cells in check. Finally, we know that smoking causes long term lung problems, circulatory problems among others. Unfortunately, the symptoms do not usually show up until the long term damage to the body is done...25, 30 or more years after one starts smoking. It makes sense, then, to never start smoking or to quit while very young.
7 :
Smoking does increase the risk and is a CAUSE of lung cancer. However there is a wide variety of other causes besides lung cancer. Cigareete and tobaco companies are FORCED to put a warning on the box that using the products INCREASES their risk for developing lung cancer. They would not do this if it wan't PROVEN. The majority of lung cancer patients have been affected by tobacco use and test have PROVEN that it was the cause for those people. BUt even if someone smokes their whole life they may luck out and never get lung cancer, or they may have other problomes because of smoknig. Basically Increased the risk is they same thing as causing it because that would be why ther person gets it. Again however non smokers are at risk beacuse there are non tobacco related casues of lung cancer also.

Someone has a life insurance policy and states non smoker but they are dying from lung cancer

Someone has a life insurance policy and states non smoker but they are dying from lung cancer?
This policy is about 18 years old and recently an agent was out to update the policy and i am not sure any changes were made as it would have been very apparent that this person smokes now. Since then they found out they are dying of lung cancer should they notify the agent that they are a smoker even though they are already dying? There is no current dec page stating if that was changed or not. Can the policy be voided?
Insurance - 5 Answers
Random Answers, Critics, Comments, Opinions :
1 :
Possibly, especially if the corner marks smoking as a possible cause of death. A lot of places will mark smoking as a cause of death even if it was through an unrelated cause so you may be out of luck. I'd go over the terms of the insurance policy very carefully, it should answer your question.
2 :
lung cancer doesn't mean the insured smokes...there are other causes, you know.
3 :
If they make a change now to add in smoking, my guess is the policy will be void. The change will likely require at least a questionnaire that asks about their current health. A diagnosis of cancer will certainly not get the policy renewed. FYI, people do get lung cancer without smoking. I believe about 10% of lung cancers are not due to smoking. That's a pretty good amount.
4 :
Better find out now if the agent really did change the policy!!!! If the agent did change the policy a new contestibility period starts. And, if this person really is dying it probly would make the policy null and void if they die within the first 2 years of the policy. Better talk to the agent now and stop that change from happening if it is in the process or has taken place. You can have serious problems when replacing the policy with another one. Call the Department of Insurance in your state and file a complaint. The agent could be in serious trouble for not looking out for the customer's best interest and negligent in his duties. This could be a lawsuit just waiting to happen. Call the Department of Insurance for help.
5 :
OK, first, you CAN get lung cancer even as a nonsmoker. That's what all those asbestos claims have been about! Second, the policy is not voided. They've probably SINCE taken up smoking. Additionally, even if they HAD lied on the application about it, it's too late for the insurance company to contest it. No problems. The payout will happen.

no no no no no no no no no no no no. it will only make it worse if you smoke it and don't even chew you'll get mouth cancer. o and if its prescribed medicine then you'll have to ask your doctor
4 :
I am not for marjuana but....it has helped some cancer patients with appetite....pain...so in this case I would say yes. BUT medical marj has been abused by people that do not need it.I am sorry I could not help you...PLEASE research it on-line or with your oncologist. Have no clue whatsoever if smoked or in food makes a difference but if you should decide to do this food would be best for you...you have to take care of your lungs...cancer or not.
5 :
it will make it worse most likely. eat it. it's stronger that way with how your body breaks it down so any you have will last longer and be more effective for whatever you are using it to help with.
6 :
I would not recommend smoking, especially if you have lung cancer - unless you are going through palliative care only. I would suggest cooking it in food. That will remove the smoke issue, and also remove any issues of bacteria/chemicals/fungi that could cause infection, especially if you have a lowered immune system (smoking marijuana is just like eating unwashed fruit and veggies - not such a huge deal for a healthy person, but for someone going through chemo it could be an issue.)
7 :
Weed will help, but Dont SMOKE it, because ALL smoke is bad for your lungs. Just melt some butter, and add broken down weed to it. Let it simmer for about 5 minutes or a little longer just incase. Only on LOW heat. Add the butter to some brownie mix following the recipe.
8 :
Smoking is bad for your lungs regardless of the substance. It would be best for you to use a vaporizer or eat it.
9 :
This is said to be a difficult question to answer but it really isn't. Medical Marijuana can be used to treat all forms of cancer--including lung cancer. The fastest way to get it in your system is to inhale, HOWEVER (and this is the catch) you must not smoke, because smoke contains harmful carcinogens that not only cause lung cancer, but make it worse. How to do you past this? You use a vaporizer. A vaporizer's job is basically to heat your herb in order to release 100% of the THC in it's gaseous form. This is what you breathe in in order to treat your lungs. Note: Marijuana does not cause cancer, the released chemicals in smoke do. This is eliminated through the use of a vaporizer. Also, you save your already vaporized remains and either smoke it (done by most cancer patients when awoken with pain at 3 in the morning), or make edibles from it. You can also make Green dragon, which is vaporized MJ soaked in 150 proof alcohol, the green liquid can be used to lace your food when in pain but do not want to smoke. Hope this info helps...

Hi I work at this shredding company and we shred books, papers, magazines, etc. However, there is so much dust where I work. After my first day on the job I would sneeze dust.

Cancer is not the biggest issue I would worry about. The chances of that are low from breathing in dust. On the other hand you can develop allergies and asthma. And something similar to black lung disease that coal miners would get from breathing in coal dust. I would definitely think about getting a mask.

According to the leading cancer research websites, cancer is caused by almost everything. My research on this question has revealed that the leading cancer research sites will tell you all the things that cause cancer and scary statistics, yet they fail to address what, about any of those things, actually causes cancer. The only thing that is actually known to cause cancer is radiation. So don't swallow any radiation sources and you should be fine. Dust isn't radioactive so I wouldn't worry if I were you.
4 :
No one knows what causes cancer and dust is not a risk factor, but why would you subject yourself to that? At least wear a mask. Call OSHA, something. You should know however, that many risk factors for several cancers tend to involve chronic irritation of tissues and this could be one of those situations.

Ad this to your research. I was 16, never smoked in my life, yet had lung cancer. You can research it under Mucoepidermoid Carcinoma. only about 54 cases in the world. Yes smoking is a major contribution to cancer, but so is if you breathe in asbestos (there have been many cases of this all around the world) All the best!

If you want to get technical about it, no-one has ever proved that smoking causes lung cancer - no-one knows the exact process involved. There is a statistical correlation between smoking and lung cancer that is of a significant size, but not an actual cause as in A causes B by means of C. Passive smoking on the other hand is far more entertaining, I could give you chapter and verse on those studies... It's also worth looking at who funded the studies, and who funds the funders.

I have a friend whom says she has lung cancer. I actually don't believe her. She is only 42 yrs. old. She said she has the opinion of 3 doctors.

Diagnosing Lung Cancer To help find the cause of symptoms, the doctor evaluates a person's medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer. The doctor also performs a physical exam and may order a chest x-ray and other tests. If lung cancer is suspected, sputum cytology (the microscopic examination of cells obtained from a deep-cough sample of mucus in the lungs) is a simple test that may be useful in detecting lung cancer. To confirm the presence of lung cancer, the doctor must examine tissue from the lung. A biopsy -- the removal of a small sample of tissue for examination under a microscope by a pathologist -- can show whether a person has cancer. A number of procedures may be used to obtain this tissue: Bronchoscopy. The doctor puts a bronchoscope (a thin, lighted tube) into the mouth or nose and down through the windpipe to look into the breathing passages. Through this tube, the doctor can collect cells or small samples of tissue. Needle aspiration. A needle is inserted through the chest into the tumor to remove a sample of tissue. Thoracentesis. Using a needle, the doctor removes a sample of the fluid that surrounds the lungs to check for cancer cells. Thoracotomy. Surgery to open the chest is sometimes needed to diagnose lung cancer. This procedure is a major operation performed in a hospital. ..........Lung cancer is difficult to detect early because symptoms usually do not appear until the disease is advanced. Symptoms depend on the location of the tumor and can include persistent cough, hoarseness or wheezing, shortness of breath, sputum streaked with blood, recurring bronchitis or pneumonia, weight loss and loss of appetite, and chest pain. Physicians use several techniques to diagnose lung cancer, including the following: Imaging Tests Chest x-rays, computed tomography (CT) scans, and magnetic resonance imaging (MRI) help locate abnormal areas in the lung. Low-Dose Helical CT A technique called low-dose helical (or spiral) CT may offer a novel approach for diagnosing lung cancer by exposing the patient to less radiation than a conventional chest CT scan while allowing the doctor to see areas of the chest normally obscured in a standard x-ray. Memorial Sloan-Kettering is now studying the effectiveness of low-dose helical CT in a clinical trial. Outside of New York, the National Cancer Institute has begun a multi-center study of the technology. Combined PET/CT Scans Memorial Sloan-Kettering's radiology department includes the best combined PET/CT imaging technology available in the United States. This is particularly important in imaging lung cancer, which can be difficult to identify on a regular CT. To address this situation, a PET (positron emission tomography) scan, which picks up the metabolic signal of actively growing cancer cells in the body, is run simultaneously with the CT scan. This improved imaging capability provides for superior treatment planning because the details of the tumor are better defined. Bronchoscopy & Biopsies A sputum sample can be analyzed for the presence of cancerous cells. Doctors may perform a bronchoscopy, which allows them to examine the bronchial passages using an instrument called a bronchoscope. This is a small tube that is inserted through the nose or mouth, down the throat and into the bronchi. During the procedure physicians may remove some tissue for analysis. A modified form of bronchoscopy called autofluorescence bronchoscopy, which can detect early invasive cancers not seen with standard x-rays or white-light bronchoscopy, is being used to detect very early lung cancer. To examine areas of the lungs that are not accessible during a bronchoscopy, physicians may perform a needle biopsy ("fine needle aspiration" or FNA) to remove a small sample of tissue for analysis.
2 :
here are the tests in step as they are done, X-ray, CAT scan, MRI and biopsy. A biopsy is necessary to check what kind of T-cell growth it is and what kind of malignancy it is.
3 :
the doctor needs to schedule you for either a ct chest with and without contrast and then possibly an MRI or PET scan. If the results are positive, then a bronch with biopsy is necessary. then doctor will then send the specimen over tot he lab for the pathologist to do a frozen section and try to diagnose the tumor
4 :
Yes, you're right. You cannot diagnose for certain without a biopsy. You may have a PET or CT that suggests, but you really don't have a histologic diagnosis till you get a biopsy. Even if she has a spot on her lung, doesn't mean she has primary lung cancer. Could be calcification, or could be breast cancer spread to the lung.

If the patientâ€™s doctor suspects lung cancer, he or she will take a detailed medical history to check all the symptoms and assess the risk factors. The assessment of the patientâ€™s medical history will be followed by a complete physical examination. The doctor will examine the patientâ€™s throat to rule out other possible causes of hoarseness or coughing, and listen to the patientâ€™s breathing and the sounds made when the patientâ€™s chest and upper back are tapped (percussed). The physical examination, however, is not conclusive. If the doctor has reason to suspect lung cancerâ€” particularly if the patient has a history of heavy smoking or occupational exposure to substances that are known to irritate the lungsâ€”he or she may order a chest x ray to see if there are any masses in the lungs. Special imaging techniques, such as CT scans or MRIs, may provide more precise information about the possibility, size, shape, and location of any tumors. Sputum analysis involves microscopic examination of the cells that are either coughed up from the lungs, or are collected through a special instrument called a bronchoscope. Sputum analyses can diagnose at least 30% of lung cancers, some of which do not show up even on chest x rays. In addition, the test can help detect cancer in its very early stages, before it spreads to other regions. The sputum test does not, however, provide any information about the location of the tumor and must be followed by other tests, such as bronchoscopy, where machines can detect cancerous cells without the need to open the chest. Lung biopsy is the most definitive diagnostic tool for cancer. It can be performed in several different ways. The doctor can perform a bronchoscopy, which involves the insertion of a slender, lighted tube, called a bronchoscope, down the patientâ€™s throat and into the lungs. In addition to viewing the passageways of the lungs, the doctor can use the bronchoscope to obtain samples of the lung tissue. In another procedure known as a needle biopsy, the location of the tumor first is identified using a CT scan or MRI. The doctor then inserts a needle through the chest wall and collects a sample of tissue from the tumor. In the third procedure, known as surgical biopsy, the chest wall is opened up and a part of the tumor, or all of it, is removed. A doctor who specializes in the study of diseased tissue (a pathologist) examines the tumor samples to identify the cancerâ€™s type and stage.

Why is painful lung action a common symptom of lung cancer

Lung cancer is such a debilitating disease. My nephew died from it last year and he was only 50. The cancer cells just eat up and destroy all the healthy tissue, invade the healthy cells and make them mutate with cancer. Your lungs have an abundance of elasticity in them and when this is destroyed, simple things like coughing can hurts. Sneezing because it cause a rush of air. They can no longer run and play hard sports because the heavy breathing alone causes difficulty for them because the lungs cannot properly move in a nice flowing motion because the elasticity is gone. At the onset of lung cancer, most don't know they have it and normal activities don't change, but as the disease progresses, the lungs become like leather, their color, which should be a nice pink, will more than likely be a nasty color. The alveoli which is air pockets that look like a bunch of grapes in your lungs, are bigger because of the strain to breath. Breathing becomes very painful but that's near the end. I watched my sister-in-law die from lung cancer. Hope this helps

Hi: I had my left lung removed due to small cell carsinoma. I am a non smoker. And you can also get lung cancer from asbestos but I use to work in a smokey casino in las vegas. but I got it and I am not going to give up My lung was removed July 2004. So never give up. And if you have a family member with it I would recomend that he or she see a onicologest and do treatments as well as surgery if they can. But never give up because of the word Cancer...
2 :
Not sure what you mean by "where" you get lung cancer. Obviously you know that lung cancer is in lung tissue (at least I hope you know) but what do you mean by "where"? If what you really meant to say is "Why does it matter where in or on your body you get cancer?", then it matters a lot. Some cancers have a higher cure rate than others, some are more aggressive than others, some metastasize more readily, some are slow-growing and some respond better to treatment. A lot depends on the primary site.
3 :
I'm assuming you're referring to the lung cancerous cells spreading to other parts of the body? This is called metastasis or advanced metastatic lung cancer. What happens in this case is that the cancer that originally started in the lungs is no longer localized to the lungs, but has gotten into the lymph/blood system and spread to other organs. The cancerous lung cells plant themselves in other parts of the body and start to grow. This is worse than localized lung cancer, so it's more likely to kill. Surgery alone wouldn't be enough to remove the spread cancer. Having localized cancer of any form is better for survival chances, as it can be operated on and removed, then possibly treated with chemo/radiation/immunotherapy in just that area to ensure the cancer is killed.
4 :
Well if you get cancer while at work, then it becomes a workers compensation deal, and then your old employer will have to pay at least part of the cost of the casket. They also need to continue your wages for a while, during the time that you are away from work getting treatment, unless they can prove that your asbestosis was caused by something away from work, like asbestos sprayed on ceilings in your home or something like that. Proving that you get lung cancer at work is more difficult in some states than others. For instance, in Oregon, it is much more difficult for the employee to prove it happened at work, while in California, it is more difficult for the employer to prove it did not happen at work. So yes it does matter where you are when they discover the cancer, and if you got it at work or while at home, or on your recreation time. Yes I am making fun of a serious subject. I hope someone got a laugh out of this - they where probably having a pretty bad day otherwise, I hope it got a chuckle out of them. My Personal History With Cancer: I started to learn about Lung Cancer when I was only 9. By 10, I knew what it is like to lose a parent to lung cancer, and by 18 I can tell you I had first hand experience in losing both parents. Funny, they say in a household where both parents smoke, that one or two of the kids might also smoke. Seems that non of the kids, and most of the grandkids never took an interest in smoking. I personally can not touch a cigarette, even the thought of it makes me uncomfortable. More recently, I have had two friends with life threatening cancer, and both have fully recovered. They used to have very high PSA counts, but that readout is now 0. They both used to get yearly screening for cancer, but the doctor said "Keep up the good work, you don't need to come back for 2 years". You see killing cancer cells is not difficult anymore. Once we began to understand how they multiply, and what environment the cancer cells multiply best in, then change to un-fertile environment, and the cancer will die off. When they test the blood of a cancer patient, they are all to acidic. Good Luck!
5 :
It doesn't matter where you get it or how you get it, its a very hard cancer to overcome and the odds are certainly against us. Not impossible for some to overcome lung cancer, but most can certainly be terminal. Personally my docs don't have an answer on how I got it, all they can tell me is that mine isn't going to go away. that doesn't mean I won't fight it til my last breath.
6 :
A lot depends on the kind of lung cancer. My mom was diagnosed with small cell in June of 2006 and died three months later. However, her brother was diagnosed with lung cancer (not small cell) in 1986, had a lung removed, underwent radiation, and lived for 21 more years before he died of heart related conditions.

No, you cannot get lung cancer from smoking one time. However, nonsmokers can develop lung cancer. Cancer can develop over time from breathing in second-hand smoke, pollution and other carcinogenic materials. Don't worry about you smoking that one time- damage to the lungs is repaired and contaminant particles are gradually removed over time (assuming you don't smoke again!)

Don`t worry, of course not but don`t do that again.

of course not. but i would still not try it anyways. lung cancer comes from years of constant smoking but it is still not a good habit to pick up

Why do we assume that non-smokers with lung cancer contracted it from second-hand smoke

Why do we assume that non-smokers with lung cancer contracted it from second-hand smoke?
Medical websites list the many ways to get lung cancer and many will state that doctors cannot say for certain where the cancer came from. What I mean by "we" is that often when the subject a non-smoker dying of lung cancer comes up, its followed with sentiments such as "...and thats why we gotta get smoking banded in saloons." Not that smoking is "good for you," but this is usually the first reaction, and not something like "...thats why Los Angeles is dangerous, there's too much smog and pollution." So Christopher Reeve's wife was stuck in rooms with second hand smoke for too much time of her life??? It must not have anything to do with the environment, which we are all to blame for? Its because of smokers?

Consider that if you smoke a pack a day for fifty years and finally get lung cancer (it often takes that long to affect the actual person smoking) then how could the second hand smoke possibly be the cause of cancer in someone who doesn't smoke at all?
2 :
Who's we? Throughout my lifetime I have been made aware of several differant causes of lung cancer, although smoking and the offspring of it is the #1 cause. Many truck drivers have contracted lung cancer from their cargo. Mostly grain drivers but there are other instances as well. Pipe Fitters especially those employeed before asbestos was outlawed are likely to contract lung cancer, also painters, construction workers, countertop finishers (granite and corian) . The list is quite long. So with all of these differant occupations effected I really don't know who we is because many lives have been effected.
3 :
because, an active smoker inhales less smoke (with nicotine) than passive smoker.. why? because, a cigarette has a filter so less nicotines are being inhaled, unlike in the case of passive smokers that inhales the smoke without a filter,.
4 :
Cancers have to be caused by something. An acidic body will encourage cancer growth but cancer needs a catalyst or carcinogen to start the cancer growth. For most people, the only carcinogens they come across in the air are second hand smoke, dust in the air, and other air pollution from industry and cars. If dust in the air from natural events caused so much cancer to be a leading cause, we would have known about it long ago. While air pollution from industry and cars is more prevalent then second hand smoke, it's not as concentrated as being stuck in a room with smokers day in, day out for years on end and it's the concentration that overwhelms the body's ability to get rid of it. While doctors may not be able to say exactly what caused any one case of lung cancer, the statistics show a strong correlation between second hand smoke and increased frequency of lung cancer.
5 :
There has never been a study performed to prove that 2nd hand smoking has ever contributed to lung cancer. But that doesn't mean I would go near second hand smoke.
6 :
I have never heard that, but if people say that, it is due to ignorance. Everybody is an expert, you know what I mean?

It could be from various other things but hey if I were to get lung cancer I'm going to blame my parents and myself I smoked for 11 years and before that I inhaled the smoke from my parents.

that's a loaded question. there are different types of lung cancer and many times, the person isn't aware of it until there are outward signs such as a lump or if something shows up on an x-ray. see the cancer society web site for staging information
3 :
I can only speak from experience. I thought I had bronchitis, went in for antibiotics, had an xray, suspicious shadow found.. follow up CT scan showed a strong possibility of lung cancer so went for biopsy. Stage iv non small lung cancer was found. Other than that, I had no other symptoms. I had extensive chemo, which had no wide effects on my tumors but have helped keep me stable for the past 3 years. Progression I was told would be distant metastasis eventually to other organs. Prognosis for me was less than a year of life with treatment, its now nearly three years with no progression. Its a daily fight winning one battle at a time, weather I win the war tho is a whole different story and one I am never too sure about. Time frames are different for everyone. I live for the future, and not worry about today. Right now, each day is a gift.

Is it possible for chronic bronchitis to turn into lung cancer

Is it possible for chronic bronchitis to turn into lung cancer?
What are the chances of getting lung cancer before the age of 20? Can you get it after smoking 2, 4 or 6 years? And back to my original question, can chronic bronchitis turn into lung cancer?
Cancer - 7 Answers
Random Answers, Critics, Comments, Opinions :
1 :
Well, first of all, chronic bronchitis is a condition usually found in the elderly so I'd be very surprised if you have that if you're not even 20. Second, I don't think it does turn into lung cancer since it's a standalone chronic condition by itself. However, it may weaken your body so that it will be easier to get lung cancer. If you're a smoker, it will take many years before you end up getting lung cancer. I've never heard of anyone who smokes getting lung cancer before their 50s or later. It is guaranteed to happen though, yes.
2 :
Um, I'm not sure but I don't think bronchitis can turn to cancer.
3 :
Chronic bronchitis will not turn into lung cancer, but people who have chronic bronchitis from smoking can also get cancer from smoking. It takes longer than a few years for most people to develop their cancers, but I've taken care of patients in their 40's with lung cancer. That may seem old to you now, but it won't when you're 40! Yesterday, I gave anesthesia to 3 patients with lung cancer. One had a wedge of lung taken out, one had a biopsy but was closed up because the tumor was unresectable, and the third had about a gallon and a half of bloody fluid taken off from around his left lung - likely malignant. Don't smoke. The end is ugly.
4 :
No chronic bronchitis does not lead to lung cancer however it does lead to pneumonia and once one has had pneumonia they tend to be suceptible to getting it again and again. You can get lung cancer at any age and it doesn't always come with smoking, although smoking is a major cause of lung cancer. I've known people who smoked for most of their lives and die of natural causes without ever having lung cancer, I've also known people who never smoked who have succumbed to lung cancer. Contrary to myth chronic bronchitis does not only happen in the elderly, it can and does happen in younger people as well who probably had their first bout of it as small children. Those with asthma are also prone to chronic bronchitis. Once one learns the early signs of bronchitis they can do things that will help prevent it from progressing and causing one to miss school or work because of the illness, flu shots help as does being physically fit to begin with, getting enough rest etc.
5 :
Chronic bronchitis cannot "turn into" cancer. They are two separate conditions. However, smokers are at high risk for both. yes, it is possible to get lung cancer at a very young age. Sometimes, this is the type of lung cancer that is not caused by smoking. I you have concerns, you need to get checked by a doctor immediately.
6 :
Bronchitis can't "turn into" lung cancer, at any age. The chances of getting lung cancer from smoking for 2,4 or 6 years are almost 0. But the chances of getting in 20 or 30 years down the road are very high. And once you get it, the chances of dying from it are also very high.
7 :
No chronic bronchitis cannot cause lung cancer but because most chronic bronchitis sufferers are smokers, they tend to be the ones that get lung cancer as well. The chance of getting lung cancer before 20 is virtually zero. It's unsual to get chronic bronchitis after smoking for only 2-6 years, most sufferers are in their 60's.

Can Lung Cancer be detected in a chest x-ray when you have pneumonia

Can Lung Cancer be detected in a chest x-ray when you have pneumonia?
I recently went in to the doctor because I had a persistent cough. It started at the beginning of summer, lasted for about 6 weeks and went away for about a month. Then my cough came back and I went to the doctor for it again. They took a chest x-ray as well as a CVC. They ultimately concluded that it was walking pneumonia and sent me off with Pulmicort Flexhaler. After a couple of days I wasn't getting better so I went back to the doctor and they gave me a z-pack, some cough medicine, and prednisone(sp?). Although my cough seems to be getting better I am still having small chest pains and it is igniting my fears of lung cancer. My question is, although I was diagnosed with walking pneumonia, would the doctor have been able to tell if a lung tumor was present in my x-ray or could there have been a mistake?
Cancer - 4 Answers
Random Answers, Critics, Comments, Opinions :
1 :
if it is large enough it would of showed on an x-ray. I would give it another week or so and then go back. Pneumonia can take 3 months to fully go away. I know someone who had a very small tumor of lung cancer and he started coughing blood, it is probably lingering pneumonia. Rest as much as possible and any doubt call for an appointment.
2 :
Chest xrays (CXR) are notoriously poor at finding lung cancers in their early stages. Any pneumonia could have been a complication of a lung tumor. Every pneumonia should have a repeat CXR 6 weeks after treatment is started. It is unlikely that your doctor saw a lung tumor on xray while a pneumonia obscures it. It is also relatively unlikely that you have a lung tumor at all.
3 :
Absolutely- that's how my sister found out that her breast cancer had metastasized after 13 years. However-if your doctor had seen a shadow on the x-ray, or anything questionable, he definitely would have ordered further tests. It's not really unusual to have chest pains if you have had a cough for a while.

3 :
Caleb you do not have lung cancer but you may have sustained lung damage. General symptoms of lung cancer The symptoms of lung cancer can be * Having a cough most of the time * A change in a cough you have had for a long time * Being short of breath * Coughing up phlegm (sputum) with signs of blood in it * An ache or pain when breathing or coughing * Loss of appetite * Fatigue * Losing weight Less common symptoms of lung cancer There are other symptoms of lung cancer that are less common. They are usually associated with more advanced lung cancer. You may have * A hoarse voice * Difficulty swallowing * Swelling of the face caused by a blockage of a main blood vessel from the head (SVCO) * Swelling in the neck caused by enlarged lymph nodes * Pain or discomfort under your ribs on your right side (from the liver) * Shortness of breath caused by fluid around the lungs (called pleural effusion) WHAT CAUSES LUNG CANCER? Smoking is the number one cause of lung cancer. Lung cancer may also be the most tragic cancer because in most cases, it might have been prevented -- 87% of lung cancer cases are caused by smoking. Cigarette smoke contains more than 4,000 different chemicals, many of which are proven cancer-causing substances, or carcinogens. Smoking cigars or pipes also increases the risk of lung cancer. The more time and quantity you smoke, the greater your risk of lung cancer. But if you stop smoking, the risk of lung cancer decreases each year as normal cells replace abnormal cells. After ten years, the risk drops to a level that is one-third to one-half of the risk for people who continue to smoke. In addition, quitting smoking greatly reduces the risk of developing other smoking-related diseases, such as heart disease, stroke, emphysema and chronic bronchitis. Many of the chemicals in tobacco smoke also affect the nonsmoker inhaling the smoke, making "secondhand smoking" another important cause of lung cancer. It is responsible for approximately 3,000 lung cancer deaths annually. Radon is considered to be the second leading cause of lung cancer in the U.S. today. Radon gas can come up through the soil under a home or building and enter through gaps and cracks in the foundation or insulation, as well as through pipes, drains, walls or other openings. Radon causes between 15,000 and 22,000 lung cancer deaths each year in the United States -- 12 percent of all lung cancer deaths are linked to radon. Radon problems have been found in every state. The EPA estimates that nearly 1 out of every 15 homes in the U.S. has indoor radon levels at or above the level at which homeowners should take action -- 4 picocuries per liter of air (pCi/L) on a yearly average. Radon can be a problem in schools and workplaces, too. Because you cannot see or smell radon, the only way to tell if you are being exposed to the gas is by measuring radon levels. Exposure to radon in combination with cigarette smoking greatly increases the risk of lung cancer. That means for smokers, exposure to radon is an even greater health risk. Another leading cause of lung cancer is on-the-job exposure to cancer-causing substances or carcinogens. Asbestos is a well-known, work-related substance that can cause lung cancer, but there are many others, including uranium, arsenic, and certain petroleum products. There are many different jobs that may involve exposure. Some examples are working with certain types of insulation, working in coke ovens, and repairing brakes. When exposure to job-related carcinogens is combined with smoking, the risk of getting lung cancer is sharply increased. A recent study published in the Journal of American Medical Association suggests that particulate matter pollution can cause lung cancer. Lung cancer takes many years to develop. But changes in the lung can begin almost as soon as a person is exposed to cancer-causing substances. Soon after exposure begins, a few abnormal cells may appear in the lining of the bronchi (the main breathing tubes). If a person continues to be exposed to the cancer-causing substance, more abnormal cells will appear. These cells may be on their way to becoming cancerous and forming a tumor. HOW IS LUNG CANCER DETECTED? In its early stages, lung cancer usually does not cause symptoms. When symptoms occur, the cancer is often advanced. Symptoms of lung cancer include: * Chronic cough * Hoarseness * Coughing up blood * Weight loss & loss of appetite * Shortness of breath * Fever without a known reason * Wheezing * Repeated bouts of bronchitis or pneumonia * Chest pain These conditions are also symptomatic of many other lung problems, so a person who has any of these symptoms should see a doctor to find out the cause. When a person goes for an exam, the doctor ask many questions about the person's medical history, including questions about the patient's exposure to hazardous substances. The doctor will also give the patient a physical exam. If the patient has a cough that produces a sputum (mucus), it may be examined for cancer cells. The doctor will order a chest X-ray or specialized X-ray such as the CT scan, which help to locate any abnormal spots in the lungs. The doctor may insert a small tube called a bronchoscope through the nose or mouth and down the throat, to look inside the airways and lungs and take a sample, or biopsy, of the tumor. This is just one of several ways in which a doctor may take a biopsy sample. A growing number of doctors are using a form of CT scan in smokers to spot small lung cancers, which are more likely than large tumors to be cured. The technique, called helical low-dose CT scan, is much more sensitive than a regular X-ray and can detect tumors when they are small. More studies on this type of screening will show whether routine screening of smokers and others at risk for lung cancer will save lives. If you are diagnosed with cancer, the doctor will do testing to find out whether the cancer has spread, and, if so, to which parts of the body. This information will help the doctor plan the most effective treatment. Tests to find out whether the cancer has spread can include a CT scan, an MRI, or a bone scan. ======= You can see a doctor and voice your concerns, but you haven't really listed any symptoms. Your lung function can be tested as well. And lay off cigarettes or weed. Marijuana has many more carcinogens than cigarettes (and RESIN) that sticks in your lungs. You only have TWO lungs...protect them.
