Lung cancer is the abnormal growth of lung cells forming a tumor that can spread to other organs of the body such as the lymph glands, adrenal glands, brain, bone and liver.
More Details:

Cigarette smoking causes most cases of lung cancer. Lung cancer is the leading cause of cancer deaths in both men and women in the United States.

Lung cancer is divided into two major categories, non-small cell lung cancer and small cell lung cancer.   This categorization depends on how the cells look when viewed under a microscope. These types of lung cancer have their own characteristics and spread differently which will determine the path of treatment that is taken.
