Nasopharyngeal carcinoma (NPC) is a rare malignancy in most parts of the world, with an incidence well under 1 per 100,000 person-years. Exceptions are the Chinese, especially the Cantonese living in the central region of Guangdong Province in Southern China. Other populations with elevated rates include the natives of Southeast Asia, the natives of the Artic region, and the Arabs of North Africa and parts of the Middle East. Intake of preserved foods at an early age has been linked to NPC risk in all population groups with increased NPC rates. Other recognized risk factors for NPC are cigarette smoking, and occupational exposure to formaldehyde and wood dust.
鼻咽癌（NPC）在世界大部分地区是一种罕见的恶性肿瘤，发病率远低于每10万人年1例。中国人是例外，尤其是居住在中国南方广东省中部地区的广东人。其他发病率较高的人群包括东南亚原住民、北极地区原住民以及北非和中东部分地区的阿拉伯人。在所有鼻咽癌发病率升高的人群中，早年食用腌制食品都与鼻咽癌风险相关。其他已确认的鼻咽癌风险因素包括吸烟以及职业性接触甲醛和木屑。
