Can you get lung cancer if your spouse smoked for years?

Yes: A small percent of folks get lung cancer without any identifiable risk factors. I've autopsied at least three people with smoker-type lung cancer who did not smoke themselves but whose spouses were heavy smokers and the house was smoke-laden. I believe this causes the disease. Hope you'll be okay. Best wishes.

Can get cancer: We know, lung cancer in "never smoked" population, if looked at as a seperate disease would rank in the top 10 lethal cancers in usa. Second hand smoke exposure is a known risk. http://goo.gl/q3itr should work with family physician to maximize overall wellness.
