Fluoridated Water Increases Risk of Cancer in Boys
On April 6, 2006, WebMD reported on a study which is to be published inside the May 2006 issue of Cancer Causes and Controls that shows a connection between fluoridated water and an increased risk of of a deadly bone cancer. Final results of this study were that boys who were raised in communities that added at least moderate amounts of fluoride to their water got bone cancer, specifically osteosarcoma, more frequently than boys who drank water with little if any fluoride.
 
The study failed to obtain the same results in girls. The more fluoride within the water during the years the boys experienced growth spurts, the larger the risk of the deadly bone cancer. Elise Bassin, DDS, author of the study and clinical instructor in oral health policy and epidemiology at Harvard said she "was astonished at the final results." She continued, "Having a background in dentistry and dental public health, [I] was taught that fluoride at recommended levels is safe and effective for the prevention of dental [cavities]," Bassin says in the statement. "All of [our analyses] were consistent in finding a connection between fluoride levels in drinking water and an increased risk of osteosarcoma for guys diagnosed before age 20, although not consistently for women." The article noted that Osteosarcoma is approximately 50% more prevalent in boys when compared to girls. Additionally, it was noted that boys generally have more fluoride in their bones than girls.
 
Also, fluoride collects in the bones, and it is more prone to accumulate in the bones during periods of rapid bone growth. A nonprofit watchdog organization, known as the Environmental Working Group, (EWG - www.ewg.org), says water fluoridation should stop until further research can refute or confirm Dr. Bassin's findings. Tim Kropp, PhD, a senior scientist at EWG told WebMD in an interview that, "About 65% of the U.S. water supply has added fluoride." He immensely important, "With evidence this strong, it only is practical to do something about it. At the moment, it makes the most sense to put fluoride in toothpaste, instead of into our water. It is not like this is a huge contaminant that will cost billions of dollars to fix. We can just stop adding it to our water it if we want to."
