Lung Cancer

Lung cancer is the leading cause of cancer death and the second most common cancer among both men and women in the United States.

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.

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. Get your home tested for radon.

People who have smoked for many years may want to think about screening for lung cancer with low-dose computed tomography (LDCT). Talk to your doctor about lung cancer screening and the possible benefits and harms. Lung cancer screening is not a substitute for quitting smoking.
