Low-Dose Computed Tomography Screening for Lung Cancer in Asia, Including Never-Smokers.

Lung cancer in never-smokers (LCINS) presents a distinct epidemiological profile in Asia, with a higher proportion of cases occurring in never-smoking women. This review examines the evidence for lung cancer screening in this population, synthesizing data on risk factors, LDCT screening, and current guidelines across Asian countries. Challenges such as overdiagnosis and economic limitations to screening implementation are discussed, and future research directions, including risk prediction and tailored screening, are highlighted.
