Eligible participants comprise current smokers with a history of ≥ 20 pack-years, former smokers who have quit within the past 15 years, non-smokers exposed to wood smoke more than 100 hours/year, or patients diagnosed with Chronic Obstructive Pulmonary Disease (COPD).\n\nSecondary objectives include assessing the 10-year mortality rate, the association of lung cancer with immunologic biomarkers, the demographic characterization of participants, the psychological impact of an LC screening program, the histological profiling of positive cases, lung function changes in at-risk individuals, and the clinical staging distribution at diagnosis.\n\nThe study will conduct annual LDCT scans, lung function tests (spirometry), anxiety and depression assessments, and serum biomarkers tests over 3 years. Positive LDCT results will adhere to LUNG-RADS guidelines and be managed by a multidisciplinary team. Prevention strategies, including tobacco cessation treatments, will be provided.
