据国内外大量文献报告,由于种族(黄种人、白种人、黑种人)或民族(如汉、满、苗、回族等)不同,某些脏器癌症的发生率也有很大差别。例如皮肤癌跟不同人种皮肤色素沉着多少有关;鼻咽癌则以中国南方人常见,移居海外的华侨也是如此;原发性肝癌是非洲班图族人最多见;子宫癌却在日本和欧美的 According to reports from a large number of documents both at home and abroad, the incidence of certain organ cancers varies greatly depending on the race (yellow, white, black) or nationality (such as Han, Manchu, Miao, Hui, etc.). For example, skin cancer is related to the degree of skin pigmentation in different ethnic groups; nasopharyngeal cancer is common in southern China, and overseas Chinese are also overseas; primary liver cancer is the most common among African Bantu people; uterine cancer is in Japan and Europe and the United States.
