We all know that lung cancer is characterized by high recurrence and high metastasis, which is why lung cancer is difficult to treat. What do patients and family members need to do? After the initial diagnosis of recurrence is made, all items of clinical staging review should be done first, so as to understand the overall condition of the whole body and all information of some lesions, so as to assess whether the patient can tolerate another operation and whether there is a possibility of complete resection. If the results of clinical staging are compatible with surgery and can tolerate reoperation, surgery should be actively performed, especially for postoperative local recurrence of the original stage I disease. For those who cannot undergo surgery, radiotherapy or chemotherapy should be administered as much as possible to kill more tumor cells when the recurring tumor is smaller, which can also reduce symptoms, pain and prolong life. The treatment difficulty of lung cancer recurrence increases and the cure rate decreases significantly. However, the main patients still have the possibility of treatment, so they should not give up the treatment prematurely. Comprehensive treatment methods should be chosen when lung cancer recurs. This is more beneficial to patients. The Department of Radiotherapy of the First Affiliated Hospital of Fujian Medical University features radiation therapy for tumors and comprehensive treatment for various common tumors. Its main treatment means include general radiotherapy, intensity-modulated radiotherapy, conformal radiotherapy, three-dimensional conformal intensity-modulated therapy and other radiation treatments for tumor patients. It is an authoritative hospital for tumor treatment in Fujian Province, and at the same time, it is a Grade IIIA comprehensive hospital, which has successfully cured many patients.
