The main questions it aims to answer are:\n\nWhat is the current status of lung cancer epidemiology, including age, gender, smoking history, and pathological subtype distribution? How do different lung cancer screening behaviors (e.g., overscreening, underscreening, guideline-concordant, and precision screening) influence the capture rate of the \"curative time window\" (defined as adenocarcinoma in situ (AIS)\u002Fminimally invasive adenocarcinoma (MIA) or pure Ground-Glass Nodules (GGNs) stage)? What are the economic costs and cumulative radiation exposure associated with these different screening patterns? Researchers will compare these screening behavior groups to evaluate the efficacy of the \"low-age, low-frequency\" screening strategy in capturing early-stage lung cancer.\n\nParticipants will be asked to:\n\nProvide their medical history and detailed records of pre-diagnosis lung cancer screening (including CT scan history).\n\nAllow researchers to collect and analyze their clinical, pathological, and radiological data from hospital records and medical databases.\n\nComplete a questionnaire regarding their screening history and health-related behaviors.",[49],"Lung Cancer","2026-05-30",{"date":52,"type":53},"2026-06-04","ACTUAL",{"date":55,"type":53},"2026-05-14",{"date":57,"type":44},"2027-06-01",{"name":5,"class":6},1]
