Undifferentiated non-keratinized nasopharyngeal carcinoma is the most common type of nasopharyngeal carcinoma, and it is particularly sensitive to radiotherapy. After the diagnosis is clear and the patient’s condition allows, radiotherapy will have a very good effect soon. If patients do not have too many underlying diseases and can be treated with chemotherapy, the effect will be better and the 5-year survival rate will be greatly increased. The early symptoms of nasopharyngeal carcinoma are relatively insidious and may only be symptoms such as nasal congestion and blood in the nose. When neck mass or intracranial complications appear, it may already be in advanced stage, so early treatment is necessary when symptoms appear.
