Generally speaking, the 5-year survival rate of early detection and early resection of lung cancer is about 50%~80%, and the specific survival time is related to the treatment method, physical condition and other factors, which varies from person to person. Lung cancer is a common primary malignant tumor of lung. Regarding how long lung cancer can live, clinically, “5-year survival rate” is often used to roughly assess the survival of tumor patients. Generally speaking, the 5-year survival rate of early detection and early resection of lung cancer is about 50%~80%. Lung cancer can be categorized into non-small cell lung cancer and small cell lung cancer, and the early 5-year survival rate of the former is about 70%~80%, while that of the latter is about 50%. Therefore, regarding the survival time of lung cancer detected early and resected early, there are obvious individual differences, which are mainly related to the treatment method, physical condition, type of disease, clinical staging and other factors, and need to be judged according to the specific situation and cannot be generalized. In summary, the prognosis of lung cancer with early detection and early treatment is good. Patients need to strengthen daily life management, go to hospitals for consultation in time and have regular review after treatment to avoid delaying their condition.
