A low-dose CT scan for lung cancer is recommended for a defined group of American adults, and two-thirds of the country does not know it is available. That comes from the 2026 Lung Health Barometer, the American Lung Association's biannual national survey, now in its eighth round, which polled a nationally representative sample of 4,000 adults ahead of World Lung Cancer Day on 1 August.

## The Rule Is Narrow and Precise

The US Preventive Services Task Force recommends [annual screening with low-dose computed tomography](https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/lung-cancer-screening) for adults aged 50 to 80 who have a 20 pack-year smoking history and who either currently smoke or quit within the past 15 years. A 20 pack-year history means a pack a day for 20 years, or two packs a day for 10. The recommendation carries a Grade B, and the Task Force says screening should stop once a person has not smoked for 15 years, or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery.
