I hope not! I don't think so, because lung cancer is predominantly caused by smoking (or second hand smoke)
2 :
its more likely caused by smoking and second hand smoke but its possibly genetic

I search people of other country and like you languages I pekin talk in spanish , but I donâ€™t know more you languages , SEE YOU LATER MY MSN rastaman_rogers@hotmail.com I LIVE IN COLOMBIA

yes!!! family history/genetics/heredity plays a MAJOR role in ANY cancer disease.
5 :
If your mother had lung cancer, but your best friends mom didn't, then you would be more ceceptable to the disease beacause you mother had it, your friend would be less ceceptable than you because her mother didn't have it!!!

well like the other answer said it does have to do with smoking but it does have to do do with genetics. If A LOT of people in ur family have lung cancer there is a good chance you might get it or be a carrier for the disease! I hope this helped!
7 :
The parents had crappy lungs and when they were reproducing, the DNA from the ungs could be sh!tty DNA and it gets passed down.

First, fewer than 10% of all cancer cases, in all types of cancer, are due to hereditary factors. As far as lung cancer is concerned, most cases are linked to smoking; people who have never smoked do get lung cancer, but in around 90% of cases smoking is implicated. There is research into the impact of family history on lung cancer, and it is likely that there is at least one faulty lung cancer gene that can be passed down in families. If you have a first degree relative (parent, sibling, child) with lung cancer, your risk of lung cancer is doubled. It is very hard to sort out the facts though, because of the major role smoking plays in lung cancer. Families of smokers will all be exposed to cigarette smoke and so have an increased risk of lung cancer whether they have inherited a faulty gene or not.

my mom was diagnosed with stage 4 non-small cell lung cancer in Nov of 2007. She never smoked. Now, my great aunt has stage 4 lung cancer - never smoked either. since they're both my mom's side of the family, i'm going to check into a blood test that can determine markers for this lung cancer being genetic.
