A study in Journal of Epidemiology suggests that drinking fluoridated top water or water with added fluoride chemicals can increase a number of cancers including bone cancer and “cancers of the oral cavity and pharynx, colon and rectum, hepato-biliary and urinary organs.” In the U.S., about 75 percent of the general population is using fluoridated drinking water.
K. Takahashi of University of Tokyo in Japan and colleagues associated age-specific and age-standardized rates of registered cancers in nine communities in the U.S. where 21.8 million people, mainly white people resided during the period from 1978 to 1992 and the percentage of people who used “optimally fluoridated drinking water.
The researchers found cancers of about two third of sites of the body were positively associated with drinking water with fluoride. Of the 36 sites, cancers of 23 sites or 64% were positively significant, 9 or 25% insignificant and 4 or 11% negatively significant.
Particularly drinking water with added fluoride were positively associated with “cancers of the oral cavity and pharynx, colon and rectum, hepato-biliary and urinary organs.” Bone cancer in males was also associated with drinking fluoridated water, which was demonstrated in rat experiments, according to the authors. A Harvard study released later also found fluoridated water is associated with bone cancer in boys.
In addition, drinking fluoridated water also increased risk for “brain tumors and T-cell system Hodgkin’s disease, Non-Hodgkin lymphoma, multiple myeloma, melanoma of the skin and monocytic leukaemia.”
The researchers suggested that “The likelihood of fluoride acting as a genetic cause of cancer requires consideration.”
