How many years you can live after lung cancer surgery is related to the stage of the tumor at the time of surgery and the type of lung cancer. The early 5-year survival rate of non-small cell lung cancer is about 75%, and the early 5-year survival rate of small cell lung cancer is about 45%. Anatomical pneumonectomy is the main treatment for early and middle stage (I and II) lung cancer, and it is also an important clinical cure for lung cancer at present. The prognosis of lung cancer patients largely depends on the TNM stage of the tumor when the disease is detected. The prognosis of patients with different clinical stages varies greatly. According to several large-scale statistical results, among non-small cell lung cancer patients in China, the early 5-year survival rate is about 75%, and the mid-term is about 55%. For small cell lung cancer patients, the early 5-year survival rate is about 45% and the mid-term rate is about 25%. Regular review should be conducted after lung cancer treatment for early detection of tumor recurrence and metastasis.
