Foremost among the cancers caused by tobacco use is lung cancer. In fact, cigarette smoking has been linked to about 90 percent of all lung cancer cases, the number-one cancer killer of both men and women. Tobacco abuse is also associated with cancers of the mouth, pharynx, larynx, esophagus, stomach, pancreas, cervix, kidney, ureter, and bladder.

Tobacco abuse harms every organ in the body. It has been conclusively linked to leukemia, cataracts, and pneumonia, and accounts for about one-third of all cancer deaths.
