Parotid gland cancer can not be treated with anything, and the main treatment methods are surgery and drug radiotherapy and chemotherapy. Surgery: parotidectomy is one of the most common surgeries for parotid gland cancer, in which the doctor will remove the diseased facial nerve together with the parotid gland and the tumor, and when there is lymph node metastasis in the neck, cervical lymphadenectomy will also be performed. Radiotherapy: Radiotherapy is mainly suitable for patients with severe tumors, patients who have not been removed cleanly by surgery, and patients with recurrent malignant tumors. The drugs often used in chemotherapy include cisplatin injection, adriamycin hydrochloride, fluorouracil injection and so on. Chemotherapy does not have high therapeutic effect on parotid gland cancer, but it can be used as an auxiliary treatment to treat patients with advanced parotid gland cancer. Parotid gland cancer patients must actively cooperate with doctors’ treatment plan and keep a good mindset.
