科学家经过二十年的研究发现,前列腺癌在美国、澳大利亚和其他西方国家中,发病率较高,平均每10个男性中就有一人可能发生前列腺癌。而在亚洲、非洲和美洲土著居民中,前列腺癌发病率却很低。但对于移民到西方并采用那里生活方式和饮食习惯的亚洲、非洲人,其发病率与当地人的发病情况也相似。 After two decades of research, scientists have found that prostate cancer has a higher prevalence in the United States, Australia and other western countries, with an average of one out of every 10 men having prostate cancer. In Asia, Africa and the Americas indigenous population, the incidence of prostate cancer is very low. But for Asians and Africans who immigrate to the West and adopt lifestyles and eating habits there, the incidence is similar to that of locals.
