>From the article: That student, Dr. Elise Bassin, wrote in yesterday's __Cancer Causes and Control__ that boys who drink water with levels of fluoride considered safe by federal guidlines are *five times* more likely to develop osteosarcoma than boys who drink unfluoridated water. Since that article is no longer available: <<http://www.courier-journal.com/apps/pbcs.dll/article?AID=/20060401/NEW S01/604010368>> osteosarcoma, a bone cancer that strikes about 400 children nationally each year. The study on osteosarcoma, which did look at fluoride at those levels, is expected to be published in __Cancer Causes and Control__, the official journal of the Harvard Center for Cancer Prevention. Harvard officials would not release an advance copy of the article, but a Wall Street Journal story said it will show that boys who drank water with approximately 0.3 to 0.99 milligrams per liter had *five times* the risk of osteosarcoma as boys drinking nonfluoridated water. This is not the first study to suggest such a connection. According to the National Cancer Institute, a federal study in 1990 showed an increased number of bone tumors in male rats given water high in fluoride for two years. And in 2001, a Harvard doctoral student reported in her thesis that boys drinking fluoridated water seem to have a higher risk of bone cancer. ... In late March, a National Academy of Sciences panel concluded that the maximum amount allowed by the federal government -- 4 milligrams per liter of water -- puts children at risk for developing mottled, pitted teeth and can weaken bones over a lifetime, making fractures more likely. In light of possible health risks, the national science panel has recommended that the maximum allowable fluoride level should be lowered. The panel said about 10 percent of children in places with water-fluoride concentrations at or close to 4 milligrams per liter develop severe tooth problems. The panel also cited studies showing a higher risk of bone fracture in people exposed to concentrations of 4 milligrams per liter or higher. ------ Is it too much to ask that people RTFA?
