Fluoride Causes Bone Cancer2005-06-29 02:12:14 AM New York - June 28, 2005 -- Newly available research, out of Harvard University, links fluoride in tap water, at levels most Americans drink, to osteosarcoma, a rare form of bone cancer (1). The Environmental Working Group (EWG), a highly-regarded Washington DC-based organization, urges that fluoride in tap water be declared a known or probable cancer cause (2), based on this and previous animal and human studies. Elise Bassin, PhD writes, in her April 2001 Harvard doctoral thesis, "...for males less than twenty years old, fluoride level in drinking water [about 1 part per million] during growth is associated with an increased risk of osteosarcoma." Further, EWG charges that Bassin's lead advisor, Chester W. Douglass, DMD, PhD signed off on her research; but told federal health officials there is no cancer link to fluoride, according to the Boston Herald (2a). Douglass is also editor-in-chief of the Colgate Oral Care Report, a newsletter that goes to dentists and is supported by toothpaste manufacturer Colgate Palmolive. "It appears Douglass violated federal research rules, according to the group's complaint, which they plan to file with the National Institute of Environmental Health Sciences," writes the Boston Herald. According to EWG, "Research dating back decades, much of it government funded, has long suggested that fluoride added to drinking water presents a unique cancer risk to the growing bones of young boys." (3) Citing a strong body of peer-reviewed evidence, including the Bassin study, EWG urges an expedited review of fluoride for inclusion in a U.S. government report of substances known or feared to be cancer-causing in humans. (2) Richard Wiles, EWG's Sr. Vice President, told the British newspaper The Observer, "I've spent 20 years in public health trying to protect kids from toxic exposure. Even with DDT, you don't have the consistently strong data that the compound can cause cancer as you now have with fluoride." (4) High-quality epidemiological studies show a strong association between fluoride in tap water and osteosarcoma in boys, reports EWG. EWG's Wiles writes, "The safety of fluoride in America's tap water is a pressing health concern....the weight of the evidence strongly supports the conclusion that millions of boys in these [fluoridated] communities are at significantly increased risk of developing bone cancer as a result." "The Harvard dissertation...obviously had merit because Bassin was awarded her doctorate," writes The Observer. Fluoride is added to water supplies in a questionable attempt to reduce tooth decay. Pro-fluoridation studies are outdated and flawed as revealed in British (5) and U.S. reviews of the literature (6). Because osteosarcoma usually develop from osteoblasts (the cells that manufacture growing bone), it most commonly develops in teenagers who are experiencing their adolescent growth spurt. Boys are twice as likely to have osteosarcoma as girls, and most cases of osteosarcoma involve the bones around the knee.

Environmental Working Group (EWG) has obtained documents suggesting that the Chairman of the Department of Oral Health Policy and Epidemiology at the Harvard School of Dental Medicine falsified reporting to the National Institutes of Health. Dr. Chester Douglass has received several years of large federal grants to study the possible relationship between bone cancer in boys and drinking fluoridated water. Reporting on the findings of this funding, he told federal officials unequivocally that there was no relationship, but the grant-funded publication he cited found exactly the opposite. In fact, the research was done by a former doctoral student of Douglass's and was the most rigorous study of its kind to date. Douglass has made the same assertion to the National Academy of Sciences panel now reviewing the safe ty of fluoridated drinking water. He is the publisher of a Colgate-funded fluoride journal. EWG has filed an ethics complaint against Douglass with the National Institute of Environmental Health Sciences (NIEHS). -------------------------------------------------------------------------- news.bostonherald.com/localRegional/view.bg Claim: Doctor fudged fluoride findings By Jessica Heslam Tuesday, June 28, 2005 - Updated: 05:00 AM EST An environmental watchdog group plans to file a complaint today with federal medical authorities claiming a Harvard doctor is fudging research findings. The Washington, D.C.-based Environmental Working Group said Dr. Chester Douglass reported no link between fluoride and bone cancer in boys, contradicting extensive research done by one of his doctoral students. Douglass, a professor of epidemiology at the Harvard School of Dental Medicine, has been given grant money, possibly more than $1 million, by the National Institute of Environmental Health Sciences to research whether there is a link between fluoride and bone cancer in boys, the non-profit group alleges. One of his dental doctoral students, Dr. Elise Bassin, did an extensive study that found a link between fluoridated tap water and bone cancer in adolescent boys, the group said. Douglass was the lead adviser on her doctoral thesis and signed off on her research, the group claims. Despite his student's findings, Douglass told federal health officials in his grant report that there is no correlation, according to the group. Douglass did not send the NIEHS the student's research but summarized it himself. Douglass is the editor-in-chief of the Colgate Oral Care Report, a newsletter that goes to dentists and is supported by toothpaste manufacturer Colgate Palmolive. Douglass could not be reached for comment last night. Bassin's research has never been published and access to it is restricted by Harvard, the group said. ``It sure seems pretty outrageous,'' said EWG spokesman Mike Casey. ``We're absolutely perplexed.'' It appears Douglass violated federal research rules, according to the group's complaint, which they plan to file with the NIEHS. - |
