Early stage lung cancer has a relatively good prognosis after surgical resection and other treatments, with a five-year survival rate of about 65% to 70%. Lung cancer is a malignant tumor of the respiratory system caused by various factors such as heredity, smoking, gene mutation, etc. Early stage lung cancer often represents a more confined lesion without lymph node and distant metastasis. In this period, it can be treated by radical surgical resection and then supplemented with radiotherapy according to the condition after surgery. After active treatment, early-stage lung cancer patients can obtain a five-year survival rate of about 65%~70%, with a good prognosis. After surgery, patients should pay attention to regular review as prescribed by doctors and maintain good living habits in daily life, such as quitting smoking, exercising properly, eating fresh vegetables and fruits, etc., which can to a certain extent reduce recurrence and prolong survival time.
