The National Lung Screening Trial, published in 2011, demonstrated that annual screening with low-dose computed tomography reduced lung cancer mortality by 20% among people aged 55-74 years. This data applied to people who had a smoking history of at least 30 pack-years and either continued to smoke or had quit within the last 15 years. This study examined the cost-effectiveness of this program.
