Nasopharyngeal carcinoma epidemiology and demographics

Epidemiology
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. While NPC is seen primarily in middle-aged persons in Asia, a high proportion of African cases appear in children. The cause of increased risk for NPC in these endemic regions is not entirely clear.
