Examination of Firefighting As an Occupational Exposure Criteria for Lung Cancer Screening.

Firefighting is known to be carcinogenic to humans. However, current lung cancer screening guidelines do not account for occupational exposure. We hypothesize that firefighting is an independent risk factor associated with the development of high-risk lung nodules on low-dose CT (LDCT). Members of a firefighter’s union underwent LDCT at a single institution between April 2022 and June 2023 within a lung cancer screening program. Results were interpreted by designated chest radiologists and reported using the Lung-RADS scoring system. Demographic and radiographic data were recorded, and summary statistics are reported. 1347 individuals underwent lung cancer screening, with a median age of 51 years (IQR 42–58), including 56 (4.2
