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, 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.
