The better the physical condition of the non-small cell lung cancer patient, the faster the postoperative recovery, which generally takes 3 months to 6 months, after which they can basically return to normal life. The prognosis for early and mid-stage non-small cell lung cancer patients is good. With the popularity of thoracoscopic TV-assisted chest surgery and comprehensive treatments such as preoperative neoadjuvant chemotherapy and postoperative adjuvant chemotherapy, the survival rate of surgically resected patients is getting higher and higher, and some in situ cancer patients can even be cured. However, lung cancer is always a malignant tumor and there is the possibility of recurrence, which requires patients to follow up and review regularly after surgery. Once the tumor recurs, chemotherapy can be administered. Chemotherapy, targeted therapy if there is a mutated target, etc. can be performed.
