Harvard Study Shows Fluoridation-Cancer Link

New Study Is One of Many Linking Fluoride to Cancer



New York -- April 7, 2006 -- Fluoridation is linked to bone cancer
(osteosarcoma) in young boys reports the May 2006 Harvard peer-reviewed
journal, "Cancer Causes and Control."



This fluoridation-cancer study, by Elise Bassin, PhD and colleagues,
follows on the heels of the National Academy of Sciences National
Research Council's (NRC) report revealing the scientific evidence
showing how fluoridation can harm subsets of the population.



"Monitor your own intake. [high water drinkers], the elderly and
people with severe renal deficiency who have trouble excreting fluoride
in their urine are likely to have increased bone-fluoride
concentrations," reports the Chicago Tribune. High fluoride levels
damage bones and teeth.(2)



Many studies link fluoride to cancer. Examples:



1954 Taylor reports more tumors and shorter lifespan in fluoride
treated mice. (3)



1956 Landmark 10-year Newburgh/Kingston fluoridation study shows more
cortical bone defects (a suspected precursor to osteosarcoma) in
children drinking fluoridated water. (4)

1977 Burk-Yiamouyiannis show cancer death rates in the 10 largest
fluoridated U.S. cities were higher and rose faster vs. the 10 largest
nonfluoridated U.S. cities after corrections for age, race, and sex..
(5)

1977 National Academy of Sciences expresses concern about a possible
water fluoridation/osteosarcoma link based on the Newburgh /Kingston
cortical bone defect evidence. (6)

1977 Congressional hearings based on the Burk/Yiamouyiannis findings
lead to fluoride cancer testing in rodents by the National Toxicology
Program (NTP) (6)



1990 NTP reports fluoride is an "equivocal" (may or may not) cause
of cancer. EPA drinking water senior toxicologist, William Marcus PhD,
reports results were suspiciously downgraded in the final report.(7)
Marcus was fired for stating the truth but rehired with back pay under
the whistle-blower's act.



1990 National Cancer Institute finds more osteosarcoma in young males
in fluoridated vs unfluoridated areas; but finds cause to dismiss the
results.(6)

1990 Procter & Gamble (P&G) makes public a 1981-1983 study showing more
bone tumors in fluoride-treated rats but claims they were not
statistically significant. Another P&G study finds a significant
increase in benign bone tumors in fluoride treated mice. (6)

1992 New Jersey Department of Health study shows osteosarcoma rates
higher among young males in fluoridated vs unfluoridated regions of New
Jersey (6). The report's title was changed to obscure connection to
fluoridation.

1993 Yiamouyiannis' analysis of National Cancer Institute's cancer
data confirms fluoridation/osteosarcoma link in males. (6)

2001 Bassin's Harvard Dissertation shows osteosarcoma in boys in
fluoridated areas is five times higher than in non-fluoridated
areas.(6). Her dissertation is uncovered in the rare books section of
library. Fluoridationists insist the study should be ignored because
it's not published and it's only one study.

2002-2005 Chester Douglass, Elise Bassin's Harvard dissertation
advisor, issues a report to his research funders at the National
Institutes of Health in 2003 in which he concludes there is no link
between fluoridation and bone cancer. He references Bassin's thesis in
support of his statement despite her conclusions which directly
contradict his claim..(9) Douglass also makes the same
misrepresentation in an earlier presentation to the British
Fluoridation Society in 2002. In 2005, Douglass becomes the subject of
a joint federal and Harvard ethics investigation. (10)

2006 NRC Panel finds cancer/fluoride link plausible.

2006 (May issue) Bassin's osteosarcoma/fluoridation study is
published in "Cancer Causes and Control," along with a letter to
the editor from Chester Douglass who cites unpublished, unfinished,
non-peer-reviewed data in an attempt to downplay Bassin's
peer-reviewed published findings of a significant link between
osteosarcoma in boys and water fluoridation.

"EPA has more than enough evidence to shut down fluoridation, right
now, with a special advisory," says retired EPA scientist, Robert
Carton, PhD. "The safe drinking water act requires the EPA to act to
protect all populations from known or anticipated harm (8)," says
Carton.

http://www.epa.gov/ogwdw/standard/setting.html



After reviewing health effects studies, EPA sets a Maximum Contaminant
Level Goal (MCLG), the maximum level of a contaminant in drinking water
at which no known or anticipated adverse effect on the health of
persons would occur, and which allows an adequate margin of safety.
MCLGs are non-enforceable public health goals. Since MCLGs consider
only public health and not the limits of detection and treatment
technology, sometimes they are set at a level which water systems
cannot meet. When determining an MCLG, EPA considers the risk to
sensitive subpopulations (infants, children, the elderly, and those
with compromised immune systems) of experiencing a variety of adverse
health effects.
