Condition: Lung Cancer

Also called: Non-small cell lung cancer; Thoracic Cancer;

Lung cancer is the leading cause of cancer death in the United States. Most lung cancer is caused by smoking, but some other exposures, such as radon, can cause lung cancer. And some people may develop it without any known risk factors. Lung cancer often develops with no symptoms or with symptoms such as weight loss that do not clearly point to the lung as a cause.
