The nasopharynx is an area behind the nose, at the centre of the head, which can only be examined by special instruments. Nearby structures are the nose, nasal sinuses, the Eustachian tube leading to the middle ear, and the base of the skull bone containing a few nerves that control sensation and movement of the eye and the face. The nasopharynx has a strong lymphatic link with the neck glands on both sides of the neck.

The causes of nasopharyngeal cancer include inherited characteristics, infection by the Epstein-Barr virus (EBV) and certain environmental factors.

Symptoms

The most common symptoms of NPC include:
