What is lung cancer screening?
The goal of screening for lung cancer is to find cancer at an early stage so that it can be treated. Lung cancer screening uses a special type of x-ray called a low-dose CT scan.
What is it like to have a CT scan for lung cancer screening?
When you have a chest CT for lung cancer screening, you lie on your back on a table that slides in and out of a tube. Inside the tube, cameras move around your body to take x-rays from different positions. The whole scan takes about 30 minutes.
