Lung cancer is cancer that forms in the tissues of the lung, usually in the cells lining air passages. It occurs when normal cell growth is disrupted, causing unchecked cell growth, which eventually causes a mass, or tumor, to form. Tumors can be benign or malignant.
If the tumor is found to be malignant, cancer is diagnosed. Lung cancer is the second most commonly diagnosed cancer in adults. In 2009, more than 219,000 people in the United States were diagnosed with lung cancer. The two main types of lung cancer are small cell lung cancer and non-small cell lung cancer. Nearly 90 percent of people diagnosed with lung cancer have non-small cell lung cancer.
