In 2013, 228,190 people in the United States will be diagnosed with lung cancer. The diagnosis of lung cancer is very serious; lung cancer kills more people than colon, breast, and prostate cancer combined. It is more common in men than in women, and African American men are 20 percent more likely than Caucasian men to have lung cancer. Early diagnosis and treatment are important for survival. Types of Lung Cancer : There are two types of lung cancer: non-small cell lung cancer and small cell lung cancer. Most people diagnosed with lung cancer have non-small cell lung cancer. For each type of cancer, the outlook and the treatment may differ. Non-small cell lung cancer occurs in the airways of the lungs or the outer part of the lungs. It usually grows slower than small cell lung cancers. Small cell lung cancers are typically in the bronchi, but can spread quickly to the rest of the body.
