Overview
Lung cancer is the deadliest type of cancer for both men and women. Each year, more people die of lung cancer than breast, colon, and prostate cancers combined.
Lung cancer is more common in older adults. It is rare in people under age 45.
Cigarette smoking is the leading cause of lung cancer.
The more cigarettes you smoke per day and the earlier you started smoking, the greater your risk of lung cancer. There is no evidence that smoking low-tar cigarettes lowers the risk.
However, lung cancer has occurred in people who have never smoked.
Secondhand smoke (breathing the smoke of others) increases your risk of lung cancer. According to the American Cancer Society, an estimated 3,000 nonsmoking adults will die each year from lung cancer related to breathing secondhand smoke.
