Overview
The incidence of nasopharyngeal carcinoma is approximately 1 per 100,000 individuals in US. It is one of the most common malignancies encountered in Asia, especially China. Patients of all age groups may develop nasopharyngeal carcinoma.
Epidemiology
Age
Patients of all age groups may develop nasopharyngeal carcinoma.
Demographics
NPC is uncommon in the United States and most other nations, representing less than 1 case per 100,000 individuals.[1] but is extremely common in southern regions of China,[2] particularly in Guangdong, accounting for 18% of all cancers in China.[3] NPC is uncommon in the United States and most other nations, but is extremely common in Taiwan and certain regions of China, accounting for 18% of all cancers in the latter nation. The cause of increased risk for NPC in these endemic regions is not entirely clear.[4] Nasopharyngeal carcinomas account for approximately 70% of all primary malignancies of the nasopharynx, and although it is rare in western populations, it is one of the most common malignancies encountered in Asia, especially China.[5]
