Who should be screened for lung cancer?

The US Preventive Services Task Force screening guidelines were updated in 2021 to recommend screenings for people who:

• Are 50-80 years old
• Smoking history of 20 pack years or more (one pack year is defined as smoking one pack of cigarettes a day for a year or an equivalent amount)
• Currently smoke or have quit smoking within the past 15 years
• Have no symptoms

What to expect during a CT scan

The CT scan takes just a few seconds, and the whole exam takes less than 10 minutes.
