Recurrence of mucoepidermoid carcinoma can usually be treated by surgery, and radiotherapy can also be considered. 1. Surgery: after the recurrence of mucoepidermoid carcinoma, if the cancer cells have not spread and the patient’s physical condition permits, the cancerous lesions can be partially removed through surgical resection, which can be an effective treatment for this disease. 2. Radiotherapy: if the cancer cells of the patient have already spread, and it is difficult to be completely removed by surgery at this time, the patient can be treated by radiotherapy, which can eliminate the malignant tumor more efficiently, thus preventing recurrence, and has low requirements on the patient’s physical condition. After the recurrence of mucoepidermoid carcinoma, patients should seek medical treatment in time to avoid the deterioration of the disease.
