Cancer mortality by site and fluoridation of water supplies.

Cancer mortality by site and fluoridation of water supplies.

Site-specific cancer mortality data for 20 United States cities have been abstracted from United States Government publications to explore further the hypothesis that fluoridation of water supplies causes cancer. Changes in mortality (standardised for age, sex, and ethnic group) between 1958-62 and 1968-72 in 10 fluoridated and 10 non-fluoridated United States cities have been examined. Of the ...

Fluoridation of water supplies and cancer mortality. III: A re-examination of mortality in cities in the USA.

Fluoridation of Drinking Water and Subsequent Cancer Incidence and Mortality

Fluoridation and cancer mortality in Anglesey.

Mortality in Anglesey from cancer (all sites), cancer of trachea, bronchus, and lung, cancer of stomach, and cancer of all other sites has been compared with mortality in England and Wales at two periods; 1949-53 (before fluoridation) and 1979-83 (after 20 years and more of fluoridation). No evidence has been found to support the hypothesis that water fluoridation affects cancer mortality.

Claims that the mortality from cancer has been increased in urban populations as a result of the fluoridation of water supplies have been given publicity in the press and on the radio and television, and questions have consequently been asked in Parliament with a view to stopping plans for further fluoridation. These. claims have been based on an analysis of the trend in cancer mortality rates ...
