The overall incidence of cancer is much the same around the world, but specific rates often vary markedly from one population to another, even when those populations are genetically similar. Epidemiologic analysis of cancer patterns in advanced and underdeveloped countries indicates that, for the most part, they are associated with behavioral, cultural, and dietary factors.
全球癌症的总体发病率大致相同,但即使在基因相似的人群中,特定癌症的发病率往往也会因人群不同而有显著差异。对发达国家和不发达国家癌症模式的流行病学分析表明,在很大程度上,这些差异与行为、文化和饮食因素有关。
