Lung cancer has long been associated with smoking. In fact 80-90% of lung cancer deaths in the U.S. are associated with cigarette smoking according to the CDC. 

But other causes include secondhand smoke, radon which occurs naturally from rocks and dirt, and other substances like asbestos, arsenic, diesel exhaust, silic, and chromium.

Here's some advice: 

  • Don't smoke
  • Avoid secondhand smoke
  • Get your home tested for radon gas
  • Follow safety guidelines at work for substances that can cause cancer

It is recommended that adults 55-80 years old who have a history of heavy smoking, currently smoke, or have smoked in the last 15 years get screened for lung cancer. 

Lung cancer screening can find cancer before the symptoms start, so talk to your doctor about your risks to help decide if screening is right for you.
