Population-based lung cancer screening can reduce mortality in people who have never smoked, study shows

New evidence from a Chinese cohort presented at the European Lung Cancer Congress (ELCC) 2026 shows that one-time low-dose computed tomography (LDCT) screening can significantly reduce lung cancer mortality in a non–risk based population, including individuals with no smoking history. The findings support reconsideration of current eligibility criteria, which still rely heavily on tobacco exposure.
