Lung cancer screening with a low-dose computed tomography (also known as low-dose CT or LDCT) scan is the only current, proven method that can detect lung cancer earlier, before symptoms occur, when it is more treatable and potentially curable.

What is Screening

Testing with a low-dose CT scan which can identify small nodules or other abnormalities in your lungs.

Who Should be Screened?

Currently, lung cancer screening is recommended (and covered by most insurance plans and Medicare) for a specific high-risk population. Individuals who meet these criteria are at the highest risk, but there is ongoing research to determine who else may have an elevated risk of developing lung cancer.

Talk to Your Doctor

Talk to your doctor about your risk for lung cancer and if a low-dose CT scan makes sense for you. Be sure to include details about your family history, environmental exposures and smoking history.

Existing High-Risk Criteria

  • You are between the ages of 55-80
  • You have a 30 pack-year smoking history
  • You are a current smoker or quit within the past 15 years

*The criteria above is recommended by the United States Preventive Services Task Force (USPSTF). If you do not meet the high risk criteria but are concerned you are at risk for lung cancer, talk with your doctor about whether screening is right for you.

Most People Screened Do Not Have Cancer

While false-positive results are possible, they indicate that something is found, but it is not cancer
