Lung cancer is one of the most commonly experienced cancers, and men are more likely than women to develop lung cancer. According to the American Cancer Society, of the 147,470 new cases of lung cancer diagnosed in 2006, more than 92,000 were men. Although lung cancer can be caused by numerous factors, including exposure to such things as asbestos and radon, the vast majority of cases are diagnosed in people who smoke.
