What age range is recommended for lung cancer screening in high-risk individuals?

The recommended age range for lung cancer screening in high-risk individuals is 55 to 80 years. This recommendation stems from evidence that shows individuals within this age group, particularly those who have a significant smoking history, have a higher incidence of lung cancer.

Screening is typically done using low-dose computed tomography (LDCT), which has been demonstrated to reduce lung cancer mortality in this demographic. The focus on high-risk individuals—including current or former smokers with a history of heavy smoking—highlights the importance of early detection in improving outcomes.

The guidelines emphasize starting screening at 55 years, as this is when the risk becomes considerably pronounced, and continuing until 80 years, as the risk remains elevated. Therefore, the upper limit of 80 is also significant in ensuring that older high-risk individuals are not excluded from potentially life-saving surveillance. The selection of this age range aligns closely with preventive health measures that aim to catch lung cancer at an earlier, more treatable stage.
