If lung cancer recurs 6 years after surgery, surgery can be taken to remove the tumor if it is single site or single recurrence; if it is multiple recurrences, radiotherapy, chemotherapy and other comprehensive treatments should be taken.
1. Single site, single recurrence: if there is a single site, single recurrence, it means that the cancer cells are still confined and the operation time is longer, therefore, surgery can be adopted to remove the tumor site, followed by radiotherapy, chemotherapy and other treatments.
2. Multiple and multi-site recurrence: this kind of situation is relatively more complicated, and it is difficult to remove the tumor by surgery, so radiotherapy, chemotherapy and targeted therapy are the main comprehensive treatments to prolong the survival period of patients.
