Lung Cancer Risk Factors

Man smoking cigarette

A number of factors may increase your risk of lung cancer. Some risk factors can be controlled, for instance, by quitting smoking. And other factors can’t be controlled, such as your family history.

Smoking
Your risk of lung cancer increases with the number of cigarettes, cigars and pipes you smoke each day and the number of years you have smoked. Quitting at any age can significantly lower your risk of developing lung cancer.

Secondhand smoke

Even if you don’t smoke, your risk of lung cancer increases if you’re exposed to secondhand smoke.

Exposure to radon gas
Radon is produced by the natural breakdown of uranium in soil, rock and water that eventually becomes part of the air you breathe. Unsafe levels of radon can accumulate in any building, including homes. Radon testing kits, which can be purchased at home improvement stores, can determine whether levels are safe. If unsafe levels are discovered, remedies are available.

Exposure to asbestos and other carcinogens
Workplace exposure to asbestos and other substances known to cause cancer – such as arsenic, chromium and nickel – also can increase your risk of developing lung cancer, especially if you’re a smoker.

Air pollution
In cities, air pollution (especially near heavily trafficked roads) appears to raise the risk of lung cancer slightly. This risk is far less than the risk caused by smoking, but some researchers estimate that worldwide about 5 percent of all deaths from lung cancer may be due to outdoor air pollution.

Family history of lung cancer

People with a parent, sibling or child with lung cancer have an increased risk of the disease.
