Harvard Study: Fluoridation associated with bone cancer in boys**
In the wake of media scrutiny and an National Institute of Health ethics investigation, a research paper from Harvard University’s ongoing study of fluoride and bone cancer was finally published*. The paper -- published 14 years after the study began reported that boys exposed to fluoridated water had a significantly higher rate of an often fatal form of bone cancer called osteosarcoma. According to the study, the boys with the highest rate of osteosarcoma were those that were exposed to fluoridated water during the ages of 6 to 8, although other years of life were also associated with increased risk – including the first year of life. These findings, which are consistent with a 1990 government study that reported the same form of bone cancer in fluoride-treated rats, have resulted in a similar degree of controversy. For example, in 1992, the top toxicologist in EPA’s Office of Drinking Water was fired after publicly expressing concern that the government was downplaying the study’s findings, while, in 2005, the principal investigator of the Harvard study (a dental professor with ties to Colgate) sparked a public outcry after it was revealed he had witheld the study’s findings from federal authorities while claiming it showed no relationship between fluoridation and bone cancer. Together, the government and Harvard studies reveal a disturbing pattern: when it comes to fluoride and cancer, politics can become a malignant force.
