U S CANCER MORTALITY SURVEY AND RELATED ANALYTIC STUDIES

一个最新的地图集，显示了三年来癌症死亡率的趋势。 《非白人的十年》出版了。 口腔疾病发病率的上升， 喉癌、食道癌和前列腺癌的发病率是其他癌症的20到100倍 白人的相应趋势。 死亡率模式 大多数站点显示出地理一致性增加的趋势， 时间 这一模式最显著的例外是 20世纪70年代，南方黑人男性前列腺癌的发病率 大西洋各州，原住民胃癌发病率上升 美国人在西南。 在一项研究中， 饮用水供应，以及超过125，000例癌症病例， 两个以人口为基础的癌症登记处所覆盖的氟化县， 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.
