Smoking is the most common cause of lung cancer, but some people who do not smoke can also have lung cancer.  Smoking is the cause for more than 80% of all lung cancers.

What You Can Do

Lung cancer is one of the few cancers that can often be prevented.  If you are a smoker, ask your doctor or nurse to help you quit.  If you don't smoke, don't start.  If your friends or loved ones are smokers, help them quit.  For help quitting, call 1-800-ACS-2345.
