Cancer and Fluoride in Drinking Water
A recent study titled "Age-specific Fluoride Exposure in Drinking Water and Osteosarcoma (United States)" has found an association between fluoride exposure in drinking water and development of osteosarcomas (a type of bone cancer).
In the May 2006 edition of the journal Cancer Causes and Control (Volume 17, Number 4, Pages: 421 – 428) researchers from Harvard stated that, "Our exploratory analysis found an association between fluoride exposure in drinking water during childhood and the incidence of osteosarcoma among males but not consistently among females."
The Harvard Student Newspaper, The Harvard Crimson also reported that Elise B. Bassin, one of the study’s authors contradicted the findings of her dissertation adviser Chester Douglass, the chair of the Oral Health Policy and Epidemiology Department at the Harvard School of Dental Medicine. Douglass’ $1.3 million dollar, 15 year study did not find a link between drinking fluoridated water and developing osteosarcoma. He said Bassin’s study is a subset of his study and that he had not been able to replicate her results. According to The Harvard Crimson, "Douglass has received widespread criticism for defending the use of fluoride while being editor of a publication funded by a fluoride toothpaste maker."
