Research has found several risk factors for lung cancer. A risk factor is anything that changes the chance of getting a disease. Different risk factors change risk by different amounts.
Examples of risk factors for lung cancer include—
Smoking and being around others' smoke.
Things around us at home or work (such as radon gas or asbestos).
Personal traits (such as having a family history of lung cancer).
Smoking and Secondhand Smoke
Cigarette smoking causes lung cancer. In fact, smoking tobacco is the major risk factor for lung cancer. In the United States, about 90% of lung cancer deaths in men and almost 80% of lung cancer deaths in women are due to smoking. People who smoke are 10 to 20 times more likely to get lung cancer or die from lung cancer than people who do not smoke. The longer a person smokes and the more cigarettes smoked each day, the more risk goes up. 1 2 3 4 5 6 7 8
People who quit smoking have a lower risk of lung cancer than if they had continued to smoke, but their risk is higher than the risk for people who never smoked.7
Smoking also causes cancer of the voicebox (larynx), mouth and throat, esophagus, bladder, kidney, pancreas, cervix, and stomach, and causes acute myeloid leukemia.
More information about cigarette smoking and lung cancer is available in CDC's Smoking and Tobacco Use fact sheets, the 2004 Surgeon General's Report, and the National Cancer Institute's (NCI) Cigarette Smoking and Cancer: Questions and Answers.
Using cigars or pipes also increases risk for lung cancer, but not as much as smoking cigarettes. For more information, visit NCI's Questions and Answers About Cigar Smoking and Cancer. 2 3 4 8 9 10 11
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. 5 12 13 14 15 16
Things at Home and Work That May Cause Lung Cancer
Several things may cause lung cancer in the workplace or even in the home—
Radon gas causes lung cancer and is sometimes found in people's homes. Radon is an odorless, colorless gas that comes from rocks and dirt and can get trapped in houses and buildings. Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer.
Examples of substances found at some workplaces that increase risk include asbestos, arsenic, and some forms of silica and chromium. For many of these substances, the risk of getting lung cancer is even higher for those who also smoke. 2 3 6 17 18 19
Other substances may increase lung cancer risk as well.
