The Bone Cancer, Fluoride Connection
April 25, 2006
Dr. Elise Bassin, while working on her PhD in epidemiology at Harvard University, conducted a study that found a significant relationship between fluoride and osteosarcoma, the most common type of bone cancer.
The study found that boys who drank fluoridated water at ages 6-8 were five times more likely to develop the cancer. The water looked at in the study had only a fourth the maximum allowable level of fluoride considered "safe" by the EPA.
These findings contradict those of Bassin's dissertation adviser, Chester Douglass, whose $1.3-million, 15-year study did not find a link between fluoridated water and osteosarcoma. He claimed Bassin's study was a subset of his study, and that he had not been able to replicate Bassin's results.
However, Douglass has received widespread criticism for defending the use of fluoride while a paid editor of the Colgate Oral Care Report, a newsletter funded by the toothpaste maker. Harvard and the National Institutes of Health are investigating whether Douglass misrepresented his research findings.
