Lung cancer is the leading cause of cancer death and the second most common cancer among both men and women in the United States.
- Each year, about 200,000 people in the United States are told they have lung cancer and more than 150,000 people die from this disease.
- About 90% of lung cancers are linked with cigarette smoking.
- When a person breathes in secondhand smoke, it is like he or she is smoking. In the United States, about 7,300 people who never smoked die from lung cancer due to secondhand smoke every year.
- After increasing for decades, lung cancer rates are decreasing nationally, as fewer people smoke cigarettes.
- Smoking can cause cancer almost anywhere in the body. Smoking causes cancers of the lung, mouth, nose, throat, voicebox (larynx), esophagus, liver, bladder, kidney, pancreas, colon, rectum, cervix, stomach, blood, and bone marrow (acute myeloid leukemia).
- Screening is recommended for people at high risk of getting lung cancer because of their smoking history and age. Ask your doctor if lung cancer screening is right for you. Lung cancer screening is not a substitute for quitting smoking.
What You Can Do to Lower Your Risk
You can help lower your risk of lung cancer in the following ways—
- Don’t smoke. The most important thing you can do to prevent lung cancer is to not start smoking, or to quit if you smoke.
- Avoid secondhand smoke. Smoke from other people’s cigarettes, pipes, or cigars is called secondhand smoke. Make your home and car smoke-free.
- Get your home tested for radon. The second leading cause of lung cancer is radon, a naturally occurring gas that comes from rocks and dirt and can get trapped in houses and buildings.
The most important thing you can do to lower your lung cancer risk is to quit smoking and avoid secondhand smoke. For help quitting, visit smokefree.gov, call 1 (800) QUIT-NOW (784-8669), or text “QUIT” to 47848 from your cell phone.
