Throat cancer is a relatively common type of malignant tumor in the head and neck area. For diagnosis and treatment, it is primarily recommended to consult an otolaryngology department. After visiting otolaryngology, related auxiliary examinations are required. Common examination methods include laryngoscopy and CT of the neck, and some patients need to consider screening for new metastatic lesions throughout the body. If feasible, a PET-CT could be considered, which is relatively more accurate. It can assess the extent and severity of the disease, which helps in clinical staging and typing. In terms of treatment, surgery is the main method, and some patients may need to consider combined treatment with radiotherapy and chemotherapy.
