In March 2021, the US Preventive Services Task Force expanded the eligibility for lung cancer screening by setting the benchmark at a 20 pack-year smoking history for those ages 50 to 80 years who are current smokers or former smokers who have quit within the past 15 years. The new criteria will boost the number of eligible adults by 87% overall, according to a modeling analysis. It also could reduce lung cancer deaths by 13% versus 10% previously.
