Nasopharyngeal carcinoma

Nasopharyngeal carcinoma (NPC) is a type of cancer that develops in the nasopharynx, and is commonly associated with Epstein-Barr virus infection. It causes obstruction of the Eustachian tube (which causes recurrent otitis media and conductive hearing loss), nasal discharge, nosebleeds, and impaired nasal breathing. NPC can metastasize to other parts of the body, such as the lymph nodes, bones, or lungs. Treatment may involve surgery, radiation therapy, chemotherapy, or a combination of these approaches.
