Overview

Lung cancer screening is a process that's used to detect the presence of lung cancer in otherwise healthy people with a high risk of lung cancer. Lung cancer screening is recommended for older adults who are longtime smokers and who don't have any signs or symptoms of lung cancer.

Doctors use a low-dose computerized tomography (LDCT) scan of the lungs to look for lung cancer. If lung cancer is detected at an early stage, it's more likely to be cured with treatment.

Discuss the benefits and risks of lung cancer screening using LDCT with your health care provider. Working together will help you decide whether screening is right for you.
