Undifferentiated non-keratinized nasopharyngeal carcinoma is a pathological type of nasopharyngeal carcinoma with a lower degree of differentiation, which should be actively treated. Nasopharyngeal carcinoma refers to malignant tumors occurring in the top and side walls of nasopharyngeal cavity. Undifferentiated non-keratinized nasopharyngeal carcinoma is a pathological subtype of nasopharyngeal carcinoma, which is the result of pathological histocytological examination. However, it is less differentiated and more malignant. It is a common type of nasopharyngeal cancer and may present with symptoms such as nasal congestion, blood in the runny nose, stuffy and blocked ears, hearing loss, diplopia and headache. Once diagnosed as undifferentiated non-keratinized nasopharyngeal carcinoma, radiotherapy and other treatment measures should be actively taken, which can be treated by radiotherapy, chemotherapy and surgery to avoid delaying the condition.
