The cure rate of lung cancer patients is basically described according to the five-year survival rate. Stage 1b lung cancer is still in the early stage, and the five-year survival rate can still reach more than 70%. Most of the patients need to undergo radical surgical resection, and take radiotherapy, chemotherapy and other treatments after surgery according to the situation. The overall prognosis is good, but it is still necessary to be specific about the type of lung cancer, the growth rate of the tumor, the immunity of the body, and other things. 1. Lung cancer type: low differentiation and high malignancy have poor prognosis and short survival period; high differentiation and low malignancy have relatively good prognosis and long survival period. 2. Tumor growth rate: if the tumor grows too fast, the tumor multiplication time is short and the 5-year survival rate is relatively low. 3. Body immunity: low immunity, strong tumor invasion ability, poor prognosis, short survival period 4. Others: age, whether smoking or not, psychological factors, etc., all have different degrees of influence on the survival period Stage 1b lung cancer needs to be rechecked once in 3-6 months according to the doctor’s instruction, so as to find out the abnormalities of the body in time and carry out targeted treatment, thus to reduce the recurrence rate after surgery and improve the cure rate and survival time of patients.
