Low-dose CT scan offers non-invasive way to screen for lung cancer
Lung cancer is the number one cancer killer of men and women in the United States, responsible for 160,000 deaths each year. Until recently, there has been no reliable way to detect lung cancer in its earliest, most treatable stage. New studies have shown, however, that a low-dose computed tomography (CT) scan can lower the risk of death from lung cancer by 20 percent in people who are at high risk.
Low-dose CT is a painless, non-invasive scan, which:
- Takes about 20 seconds
- Does not require blood work
- Does not require IV
- Is covered by most insurance plans
During the screening, you will change into a patient gown and lie flat on the scanning table. You will be asked to hold your breath during the scan to limit the motion of your lungs while the radiologist takes numerous X-ray images of your lungs from different angles.
