Screening – Lung Cancer

Screening – Lung Cancer

ScreeningExternal means testing for a disease when there are no symptoms or history of that disease. 

The only recommended screening test for lung cancer is low-dose computed tomography (also called a low-dose CT scan, or LDCT). In this test, an X-ray machine scans the body and uses low doses of radiation to make detailed pictures of the lungs.

Who Should Be Screened?

The U.S. Preventive Services Task Force recommendsExternal yearly lung cancer screening with LDCT for people who—

  • Have a history of heavy smoking, and
  • Smoke now or have quit within the past 15 years, and
  • Are between 55 and 80 years old.

Heavy smoking means a smoking history of 30 pack years or more. A pack year is smoking an average of one pack of cigarettes per day for one year. For example, a person could have a 30 pack-year history by smoking one pack a day for 30 years or two packs a day for 15 years.

This decision aidExternal from the Agency for Healthcare Research and Quality will help prepare you to talk with your doctor about whether lung cancer screening is right for you.

Lung cancer screening has at least three risks

  • A lung cancer screening test can suggest that a person has lung cancer when no cancer is present. This is called a false-positive result. False-positive results can lead to follow-up tests and surgeries that are not needed and may have more risks.
  • A lung cancer screening test can find cases of cancer that may never have caused a problem for the patient. This is called overdiagnosis. Overdiagnosis can lead to treatment that is not needed.
  • Radiation from repeated LDCT tests can cause cancer in otherwise healthy people.
