Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma, or nasopharynx cancer, is the most common cancer originating in the nasopharynx, most often in the postero lateral nasopharynx or pharyngeal recess, which accounts for half of cases. It occurs in both children and adults, differs significantly from other head and neck cancers in its occurrence, causes, clinical behavior, and treatment, and is far more common in parts of East Asia and Africa than elsewhere, with viral, dietary, and genetic factors implicated and a higher occurrence in males. It is a squamous cell carcinoma of an undifferentiated type.
