How to avoid lung cancer?

Interesting finding:: Don't take high doses of beta carotene if you are a heavy smoker thinking it will help you...It may actually increase your risk of lung cancer! not smoking is probably the best way to decrease your risk. Radon can increase risk as well. Beta-carotene and vitamin e aren't effective at decreasing lung cancer risk: http://www.Cancer.Gov/cancertopics/pdq/prevention/lung/healthprofessional/page1.

Several things:: Don't smoke. Avoid secondary smoke. Have your basement checked for radon. Watch our for asbestos. Avoid air pollution if possible. When testing to see if smoking causes cancer, they found that it caused cancer in rats but not mice. They noted that mice tended to hold still and breath as little as possible when their cages were filled with smoke. Rats did not. So the rats got cancer. B a mouse.

Don't smoke: That's the biggest risk
