It depends. Because the scan comes with its own risks, you should talk to your doctor about this screening. It is generally recommended only for people who are between 55 and 74 years old, have a smoking history equivalent to a pack a day for 30 years, and currently smoke or have quit within the past 15 years. Private insurers and Medicare cover a once-yearly low-dose CT scan for people who are eligible.
