Lung Cancer

If you smoke, or have quit within the past 15 years, our low-dose CT (LDCT) lung cancer screening test could save your life. It helps detect lung cancer early when it's easier to cure. The low-dose CT scan uses less radiation than a regular CT scan and does not require any needles for contrast dyes. Talk to your doctor to see if a low-dose CT lung cancer screening is right for you.
