U S CANCER MORTALITY SURVEY AND RELATED ANALYTIC STUDIES

一份最新的地图图集，显示了三年来癌症死亡的趋势 出版了《非白人中的几十年》。口腔发病率的上升， 喉癌、食道癌和前列腺癌的发病率要高出20到100倍 而不是白人中的相应趋势。年的死亡模式 大多数地点都显示出增加地理一致性的趋势 时间到了。这种模式最显著的例外是出现在 20世纪70年代南方黑人男性前列腺癌发病率 大西洋各州，原住民胃癌发病率上升 西南部的美国人。 在一项对氟污染县超过230万癌症死亡病例的研究中 饮用水供应，以及#年超过125,000起癌症病例 两个以人口为基础的癌症登记所覆盖的氟化县， 我们没有发现癌症风险的趋势可以归因于 饮用含氟饮用水。

An updated atlas of maps illustrating cancer mortality trends over three decades among nonwhites was published. The rise in rates of oral cavity, laryngeal, esophageal and prostate cancers were 20 to 100 times greater than the corresponding trends among whites. The mortality patterns for most sites showed trends towards increasing geographic uniformity over time. The most notable exceptions to this pattern were the emergence in the 1970s of such rates for prostate cancer among black men in the South Atlantic states, and rising rates for stomach cancer among Native Americans in the Southwest. In a study of over 2.3 million cancer deaths in counties with fluoridated drinking water supplies, and over 125,000 incident cancer cases in fluoridated counties covered by two population-based cancer registries, we identified no trends in cancer risks that could be attributed to the consumption of fluoridated drinking water.
