Lung cancer

Cancer is a disease in which cells in the body grow out of control. When cancer starts in the lungs, it is called lung cancer. Lung cancer is the leading cause of cancer death among both men and women. More people die of lung cancer each year than of colon, breast and prostate cancers combined.

Lung cancer risk factors

Smoking is the most common risk factor for developing lung cancer. Eight out of 10 lung cancers are caused by smoking.

Other risk factors include being exposed to:

  • radon, diesel exhaust or other airborne substances, such as asbestos
  • secondhand tobacco smoke

  • difficulty breathing
  • wheezing
  • shortness of breath
  • hoarseness

Lung cancer screening

Lung cancer screening is done to find lung cancer early, when treatment works better.

The Centers for Medicare & Medicaid Services recommends lung screening if you are between the ages of 50 and 77 if all the criteria below apply to you:

  • You have no signs or symptoms of lung cancer (coughing up blood, trouble breathing, lots of infections, fatigue and unexpected weight loss).
  • You smoke now or have quit within the last 15 years.
  • You have a history of heavy smoking (20-pack-year history). This means that you have smoked the equivalent of 1 pack of cigarettes each day for 20 years or 2 packs each day for 10 years.

Check with your insurance provider if you can get screening until age 80.
