These percentages will increase significantly as total fluoride exposure from a variety of sources continues to increase and as more and more people are exposed for longer periods of time. A rare form of bone cancer , osteosarcoma, is increasing dramatically in teenage boys aged 9 to 19 who live in fluoridated areas of America, but not in the non-fluoridated areas. A 1992 New Jersey Department of Health report found that osteosarcoma rates were 3 to 7 times higher in its fluoridated areas. Fluoride was found to be an equivocal carcinogen in 1990 by the National Cancer Institute Toxicology Program. By 1997, there were more than 80 references linking fluoride to cancer.
Fluoridated water increases the cellular uptake of toxic heavy metals.
Studies of children living in fluoridated Massachusetts and Georgia found elevated levels of lead in their blood . Lead is associated with aggressive behavior, delinquency, and attention disorders all predictors of future criminal behavior. Children who have been poisoned by lead are less able to handle stress and are more prone to violent outbursts. If the average were to drop just five points . . . Lead levels dropped in two community water systems when fluoride was discontinued.
