After treatment, stage 1b lung cancer can obtain a five-year survival rate of about 45%-75%. The statement of complete cure is slightly absolute, but recurrence can be reduced through regular review and other methods.
Lung cancer is a malignant tumor of the respiratory system caused by many factors, such as smoking, environment, heredity, etc. Stage 1b is one of the TNM stages of lung cancer, i.e., T2aN0M0, which stands for the largest diameter of the primary tumor is 3 cm, or it involves the main bronchus but does not involve rondulet, etc.; there is no lymph node metastasis; and there is no distant metastasis.
This period belongs to the early stage of lung cancer, the lesions are relatively limited and mild, and can mostly be treated by radical surgical resection. After active treatment, the five-year survival rate of patients with stage 1b lung cancer is about 45%-75%. Although the stage is early, there is still a certain recurrence after surgery, so it is necessary to follow the doctor’s instructions for regular checkups and maintain good living habits.
