Most people in the United States who develop nasopharyngeal
cancer (NPC) have no obvious risk factors, so their cancers could not
have been prevented.
Because certain dietary factors have been linked with NPC
risk, reducing or eliminating them may lower the number of cases in
parts of the world where NPC is common, such as southern China,
northern Africa, and the Arctic region. Descendents of Southeast Asians
who immigrated to the United States and eat a typical "American diet,"
for example, have lower risk of developing NPC. But these dietary
factors are not thought to account for all cases of NPC in most other
parts of the world. Other factors, such as genetics, are likely to play
a part as well.
