Smoking Increases Risk For Lung Cancer
Lung cancer is the leading cause of cancer deaths in both men and women. Smoking causes 80 to 90 percent of cases of lung cancer. Don’t smoke, and avoid secondhand smoke.
Cigarette smoking causes lung cancer, and increases the risk for many other types of cancer. People who smoke are 10 to 20 times more likely to get or die from lung cancer than people who don’t smoke. The longer a person smokes and the more cigarettes smoked each day, the higher the risk.

Smoke from other people’s cigarettes (secondhand smoke) causes lung cancer as well. Secondhand smoke contains more than 4,000 chemicals, more than 50 of which cause cancer in people or animals.
Every year, about 3,000 nonsmokers die from lung cancer due to secondhand smoke.
