Parotid tumor recurred after one year the main treatment includes surgical resection, radiotherapy, chemotherapy and so on. 1. Parotid tumors are mainly classified into benign and malignant tumors, both of which have a certain chance of recurrence. 2. Surgical resection is still the main treatment for recurrence of parotid tumor after one year. It can also be combined with radiation therapy, which can be external irradiation or 125I intra-tissue irradiation. Salivary gland malignant tumors have the possibility of distant metastasis, especially adenoid cystic carcinoma and salivary gland ductal carcinoma. Therefore, postoperative treatment can also be combined with chemotherapy, but no very effective chemotherapeutic agents have been found yet. If the parotid tumor recurs after one year, it is recommended to go to the hospital in time and give targeted treatment or therapy under the doctor’s guidance.
