Screening
Low-dose computed tomography (CT) for lung cancer screening in high-risk adults over 40 years with significant smoking exposure reduces lung-cancer mortality.[104][105][106]
Recommendations
The US Preventive Services Task Force and the American College of Radiology recommend annual low-dose CT in:[107][108]
adults aged 50-80 years, with
a 20 pack-year history of smoking, who
currently smoke or have quit within the past 15 years.
The USPSTF recommends that screening should be stopped when a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the likelihood of having curative lung surgery.[107]
The National Comprehensive Cancer Network recommends screening for lung cancer with low-dose CT in high risk adults:[109]
aged ≥50 years, with
≥20 pack-year history of smoking.
Shared decision-making is recommended in candidates for screening, including a discussion of the benefits and risks of screening.[109]
The American Cancer Society recommends annual low-dose CT in people:[110]
aged 50-80 years, with
at least a 20-pack-year smoking history, who
currently smoke or have previously smoked.
