What are the causes for lung cancer?
What causes lung cancer? I need to know what the tobacco smokes does to the cells to cause them to not function well. Like does the smoke change the cell cycle or like stops it or somethin?

Smoking, pollution, asbestos, and genetics.

I'm no scientist but I believe that the smoke causes tar to build up on the cell lining of the lungs. Carcinogens in the tar eventually ooze into the cell tissue, making them "wig out". Some turn cancerous and eventually develop into cancer.

smoking puts you at risk if it is in your genetics
4 :
ok first of all tobacco smoke KILLS the cells. people that are constant smokers also get a black tarry substance in their lungs and that leads to lung cancer.

http://www.cancer.gov/cancertopics/types/lung This web site has a lot of good information on it

It slows it, yes. It mainly just cuts of the oxygen. Slowly less and less O2 can make it through and cells start to die. You also have to remeber cancer is a mysterious thing. We known disrruptions in the cell's chemistry mess up the dna or force the cell through a second protophase, but their so many variable in the chemistry of a cells you have to look at statistics for info. Like Colon cancer is twice as common in Japan, but breast cancer is twice les common there. No one knows quite why, but it has something to do with our enviroments.

smoking; asbestos; pollution; and chemical inhalation. in regard to cell desruction--smoke deprives lungs of oxygen and the cells die. lung tissue then degenerates and then the lung cannot function. now you have a host of variable problems. if you really need specific info contact american lung association for their literature on this subject. they can provide all you need.

Smoking being a carcinogen, produces an above normal amount of white blood cells, outnumbering the balance of the correct amount of the red cells. When the white takes over, an infection sets in which can lead to a serious condition. Not only the lungs get affected, but the entire body does. If there aren't the adequate healthy red blood cells in the body, sickness is imminent.

breast cancer. It will often go to the lungs, bones, liver, and brain and still be breast cancer. I just went today for a pet scan to see if that is my present problem. Say a prayer for me. O.K? As a child, my house was filled with second hand smoke and that's a cause, too. Our white kitchen cabinets turned yellow from all the smoke. And I think smoking is the biggest cause.

Lung cancer is the rapid growth of abnormal cells in the lung. It can start anywhere in the lungs and affect any part of the respiratory system. Smoking is the greatest risk factor for lung cancer. Lung cancer is the leading cause of cancer deaths in both men and women. Fewer than half of the people who develop lung cancer live 1 more year. And only 15% of people who develop lung cancer live for 5 more years. Most lung cancer is caused by smoking. Harmful substances in tobacco smoke damage the lung cells. Secondhand smoke is also a risk factor for lung cancer. Besides smoking, exposure to harmful substances such as arsenic, asbestos, radioactive dust, or radon can increase the risk for lung cancer. If you have more than one of these risk factors—for example, you are a smoker and you are also exposed to asbestos—you greatly increase your risk of developing lung cancer. Radiation exposure from work, medical, or environmental sources may also increase your risk for lung cancer. There are two main types of lung cancer: small cell lung cancer and non–small cell lung cancer. Each looks different under a microscope and grows, spreads, and is treated differently. Non–small cell lung cancer is more common than small cell lung cancer. More than 80% of all lung cancers are non–small cell cancer. It generally grows and spreads more slowly than small cell lung cancer. About 20% of lung cancers are small cell. This type of cancer grows very rapidly and in more than 80% of people has already spread to other organs in the body by the time it is diagnosed. Small cell lung cancer is more strongly related to smoking than non–small cell cancer.

Here is some biased and incomplete research: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=1571278&dopt=Abstract http://www.pnas.org/cgi/content/abstract/0401422101v1 http://www.upmccancercenters.com/news/upci_news/2004/093004_cigarette_smoke.html The body is quite capable of repairing cell damage. Why do some people get cancer while others exposed to the same carcinogen, even at higher doses, never have cancer? "After twenty years of research and therapy with over 31,000 patients, Dr. Hamer finally established firmly, logically and empirically how biological conflict-shock results in a cold cancerous or necrotic phase and how, if the conflict is resolved, the cancerous or necrotic process is reversed to repair the damage and return the individual to health." - http://www.newmedicine.ca/overview.php
