Because each patient’s condition, postoperative treatment program, and physical condition are different. So the survival time after surgery for lung cancer without metastasis cannot be determined. It is impossible to give a specific judgment on how long lung cancer without metastasis can survive after surgery. Some patients with early detection of lung cancer and well-targeted post-surgery convalescence program can usually control the disease effectively and may not even affect their life expectancy. However, some patients have poor physical quality and relax their vigilance after surgery, failing to take effective measures in time, which may lead to recurrence of lung cancer. It can be seen that after lung cancer surgery, one should not take it lightly and should carry out auxiliary treatment under the guidance of medical personnel. Commonly, there are postoperative adjuvant radiotherapy and chemotherapy. The fact that lung cancer has not metastasized indicates that the disease is at the early stage, and if timely treatment is received, usually the prognosis will be good.
