More deaths are caused each year by tobacco use than by ALL DEATHS from human immunodeficiency virus (HIV), illegal drug use, alcohol use, motor vehicle injuries, suicides and murders COMBINED.
Cancer was among the first diseases linked to smoking.
Lung cancer is the leading cause of cancer death, and it is primarily caused by cigarette smoking.

The risk of smoking-caused cancers increases with the number of cigarettes smoked and the number of years of smoking, and it decreases after quitting completely.
Cancer-causing chemicals (called carcinogens) in tobacco smoke damage important genes that control the growth of cells, causing them to grow abnormally or to reproduce too rapidly.
Cigarette smoking is a major cause of esophageal cancer in the United States.
