The average life expectancy after surgery for early stage lung cancer is not generalizable and is related to the patient’s condition and staging. The five-year survival rate of early stage non-small cell lung cancer is around 75%, while the five-year survival rate of early stage small cell lung cancer is around 45%. Lung cancer is a malignant tumor that occurs in the lungs. Clinical symptoms are mostly insidious, mainly manifested as cough, hemoptysis, wheezing, fever and so on. Early stage lung cancer is usually stage I. At this time, the tumor is located in the lung tissue and has not yet metastasized. Most of early non-small cell lung cancer patients can be cured through surgical treatment, and the five-year survival rate can reach about 75%, while the five-year survival rate of early small cell lung cancer is relatively low, about 45%.
