Lung screening is a preventative medical test used to detect lung cancer at an early, more curable stage, before someone shows any symptoms. 
The only recommended test for lung screening is a low dose CT scan (computed tomography). It is often called a low dose-CT or LDCT.

This CT scan is quick and painless. No needles, no dyes, no injections, no need to remove any clothing or shoes. 

The entire screening process takes less than 10 minutes.

Testing may be covered by insurance if you meet certain criteria.  If insurance does not cover the test, there are programs that offer the test at a low cost.

Medicare and many private health insurance plans cover lung screening. It depends on the type of plan you have and if you meet the criteria.

If you are a current or former smoker over the age of 50, you are at highest risk for lung cancer.

While smoking is the leading cause of lung cancer, there are other environmental, genetic, and health factors that contribute to the risk for lung cancer. Exposure to environmental toxins such as radon gas,  a history of lung cancer in your family, and other risk factors are included in the American Cancer Society’s list of  Lung Cancer Risk Factors.

It is important to discuss your risk for lung cancer with your health provider.

No. The only thing required to have lung cancer is having lungs.  Smoking increases your risk for lung cancer, but not smoking does not eliminate your risk.
