Lung Cancer Screening: Low-Dose CT Scan

Test Overview

Screening tests help your doctor look for a problem before you have symptoms. Lung cancer screening is a way to find some lung cancers early, when a cure is more likely and when cancer is more treatable.

If your doctor recommends lung cancer screening, you'll have a low-dose computed tomography (CT) scan of your chest once a year. During the test, you will lie on a table that is attached to the CT scanner, which is a large doughnut-shaped machine. The CT scanner sends low-dose X-rays, or radiation, through your chest to make detailed pictures. A low-dose CT uses much less radiation than a regular-dose CT scan. A doctor looks at the pictures of your lungs for growths, called nodules, that could be cancer.
