Lung cancer is a complex disease to treat and understand. What many people don't know is that lung cancer causes more deaths than the next three most common cancers combined (colon, breast and prostate). Understanding the basics of lung cancer is an important step in preventing lung cancer deaths. Knowing the facts makes managing your health and talking with your doctor much easier.
