Weak Link on Fluoride and Cancer Is Backed
A panel of scientific experts today endorsed the findings of a Federal investigation showing that a compound widely used to fluoridate public water supplies may cause bone cancer in male rats.
Rat Study Reignites Dispute On Fluoride
A long-smoldering dispute over the safety of fluoridating public water supplies has flared anew, forcing the nation’s top health officials to reevaluate the risks and benefits of using fluorides to reduce tooth decay. The latest review was triggered by a Congressionally mandated study that recently reported evidence that high doses of fluoride may cause cancer […]
Caries Preventative Already Has One Rap Against It
The NTP’s findings will make it difficult for the Environmental Protection Agency (EPA) not to classify fluoride a carcinogen, thereby terminating 40 years of public-water fluoridation in the United States.
Don’t Drink the Water? Brush your teeth, but the fluoride from your tap may not do much good — and may cause cancer
Government researchers have new evidence that casts doubt on the benefits of fluoridation and suggests that it is not without risk. The most incendiary results come from the National Toxicology Program (NTP), which in 1977 was ordered by Congress to determine whether fluoride causes cancer. This week NTP plans to release data showing that lab rats given fluoridated water had a higher rate of a rare bone cancer called osteosarcoma.
Fluoride Linked to Bone Cancer in Fed Study
Fluoride appears to have caused bone cancer in rodents in a recently completed National Toxicology Progran (NTP) study, and the chemical is now at risk of being classified a carcinogen, according to internal documents and statements obtained from the Environmental Protection Agency (EPA).
