Non-small cell lung cancer is the most common type of lung cancer. It occurs when abnormal cells begin growing on or in the lungs, usually as the result of exposure to a known carcinogen. There are several different types of treatment for non-small cell lung cancer, including chemotherapy and surgery. The success of any individual treatment depends largely on the patient's current state of health, the stage of the cancer and the success of previous treatments.
