As of 2010,<unk>  resulted in 65,000 deaths globally up from 45,000 in 1990.<unk>  is uncommon in the United States and most other nations, representing less than 1 case per 100,000 in most populations. but is extremely common in southern regions of China, particularly in Guangdong, accounting for 18% of all cancers in China. It is sometimes referred to as Cantonese cancer (廣東癌) because it occurs in about 25 cases per 100,000 people in this region, 25 times higher than the rest of the world. It is also quite common in Taiwan. This could be due to the Southeast Asian diet or that Southern Chinese people such as the Cantonese and Taiwanese have Southeast Asian ancestry (such as the proto-Kra-Dai speaking peoples and proto-Austronesian peoples) via ancient intermarriages with Han Chinese from Northeast Asia which led to the transmission of a genetic risk for nasopharynx cancer. While<unk>  is seen primarily in middle-aged persons in Asia, a high proportion of African cases appear in children. The cause of increased risk for<unk>  in these endemic regions is not clear. In low-risk populations, such as in the United States, a bimodal peak is observed. The first peak occurs in late adolescence/early adulthood (ages 15–24 years), followed by a second peak later in life (ages 65–79 years).
