Fluoridation, Cancer: Did Researchers Ask The Right Questions?
By Sharon Begley

WHEN HEALTH OFFICIALS decided to add fluoride to the water supply of
Grand
Rapids, Mich., in 1945, they plunged ahead despite the lack of a
rigorous,
large-scale study of the risks and benefits. And for most of the next
60
years, fluoridation research has gone pretty much like that. It has not
been
science's finest hour.

Questions about fluoridation have returned with renewed vigor because
of
allegations of scientific misconduct against a prominent researcher at
the
Harvard School of Dental Medicine. The Environmental Working Group, an
advocacy organization in Washington, charged last month that Chester
Douglass misrepresented an unpublished study about bone cancer and
fluoridated tap water. In written testimony to the National Research
Council
last year, Dr. Douglass said he had found no evidence that fluoridation
increased risk of osteosarcoma, a rare bone cancer. But a 2001 study he
cited, and oversaw, found that boys who drink fluoridated water have a
greater risk of developing the disease. (Dr. Douglass did not respond
to
requests for comment.)

More interesting than what Dr. Douglass said or didn't say, however, is
the
study he swept under the rug. It was conducted by one of his doctoral
students, Elise Bassin. She started with the same raw data as her
mentor --
139 people with osteosarcoma and 280 healthy "controls" -- but saw a
way to
improve on it. Since most of the 400 people diagnosed in the U.S. each
year
with osteosarcoma are kids, and since any ill effect of fluoride would
likely come when bones are growing most quickly, she focused on the 91
patients who were under 20.

HER RESULT: Among boys drinking water with 30% to 99% of the fluoride
levels
recommended by the U.S. Centers for Disease Control and Prevention, the
risk
of osteosarcoma was estimated to be five times as great as among boys
drinking nonfluoridated water. At 100% or more, the risk was an
estimated
seven times as high. The association was greatest for boys six to
eight.

To be sure, one study proves nothing. Moreover, Dr. Bassin hasn't
published
her core findings (though in 2004 she and colleagues published a
description
of their methodologies). As Boston University epidemiologist Richard
Clapp
says, "Peer review picks up things that even doctoral students at
Harvard
might miss."

So I asked scientists to read the study. BU's Kenneth Rothman, founding
editor of the journal Epidemiology, called it of "publishable quality."
Zeroing in on young patients, he said, was good science: "If there were
an
adverse effect of fluoride, it's possible an effect of early exposure
would
be manifest in the first 20 years of life - but not after." Looking at
all
ages, in other words, could conceal any link between fluoridation and
cancer.

Besides focusing on kids, Dr. Bassin and her colleagues found out where
each
cancer patient ever lived, and what kind of water they drank when.
Other
studies have just noted what water a patient was drinking at the time
of
diagnosis. The problem with that is, you risk classifying someone as
drinking nonfluoridated water who in fact drank fluoridated water when
it
mattered -- in childhood. The result is that the osteosarcoma rates of
people drinking fluoridated water might look no different from those of
people drinking nonfluoridated. "She did great shoe-leather
epidemiology,"
says William Maas, head of oral health at the CDC and a supporter of
fluoridation.

PREVIOUS STUDIES have been contradictory. A 1991 animal study by the
National Toxicology Program concluded that fluoride might raise the
risk of
osteosarcoma, but only in male rats, not female. Also in 1991, a
scientist
at the National Cancer Institute found "an unexplained increase" in
osteosarcoma in men under 20 in fluoridated communities. Most human
studies,
though, provide "no credible evidence for an association between
fluoride in
drinking water and the risk of cancer," said a 1993 NRC report.

But when you look carefully at the negative studies, you have to
wonder.
Some investigated a link to all cancers; because osteosarcoma is rare,
an
increase would be unlikely to show up in that vast sea. Other studies
were
tiny, or included adults as old as 84, which would wash out effects
that
target kids. Most categorized osteosarcoma patients as drinking
fluoridated
or nonfluoridated water based on where they lived at diagnosis, not as
kids.
Concerned about such lapses, the NRC report called the studies "of
limited
sensitivity."

Even if fluoridation causes just a few hundred cases of osteosarcoma
every
year, does the public health benefit justify that risk? "When we
started
fluoridating water, we thought to get the benefits it would have to get
incorporated into the enamel before the tooth erupted," which happens
only
if you swallow it, says the CDC's Dr. Maas. But that turns out not to
be so.
Topical fluoride, as in gels and toothpaste, works at least as well.

Most proponents now say fluoridation cuts the rate of tooth decay 18%
to
25%. How much is that? Less than one tooth surface. "The absolute
impact of
18% or even 25% is low," says Stephen Levy of the University of Iowa,
who
supports fluoridation.

The next authoritative report on fluoridation will be the NRC's. One
scientist close to the committee thinks it may be released this fall,
months
later than expected. "We thought this was going to be routine," he
says. "It
wasn't." With fluoridation, it seldom is.

We'll help you out. This is how the American Dental Association (ADA)
instructs it's obedient foot soldiers to respond.  This is from an
e-mail that was sent 7/22/05 to their members and sympathizers in a
knee-jerk attempt to dismiss this well-researched news report showing a
cover up of science linking fluoride to bone cancer probably more to to
retain the ADA's  political viability with legislators, whom should be
very embarrassed that fluoridation is supported with these weak and
non-scientific talking points. (Our talking points are in parentheses)

July 22, 2005

A forum for breaking news and
timely information from the ADA

 Water Fluoridation and Alleged Risk of Rare Bone Cancer

The Wall Street Journal (July 22, Section B-Market Place, page 1) and
other news outlets are reporting that a Harvard University doctor was
charged with misrepresenting the findings of a doctoral student's
thesis that reportedly found that fluoridated water increases the risk
of osteosarcoma (a rare bone cancer). Harvard University is conducting
an investigation into the matter. Your local media may report on this
story, and your patients may ask you about it. We will post a brief
media statement about this issue on ADA.org.

To help you respond to patient inquiries, the ADA provides the
following points:

Recent news reports may be alarming people unnecessarily about the
safety of water fluoridation.

(How is it "alarming people unnecessarily" to tell people about studies
showing their  drinking water caused bone cancer and worse that the
findings are being cover-up.. This is just one of many studies  linking
fluoride to cancer in general and fluoride to bone cancer,
specifically. We think its just alarming the ADA whose political
viability is being diminished.)

We're talking about one doctoral student's paper, a paper that has not
been published in a scientific journal and therefore has not been
available for peer review. Peer review is a process where a group of
experts review studies prior to publication to determine if the study
is designed well and if the conclusions are valid.

(What the ADA isn't telling you is that  PhD theses (actually
dissertations) usually go through extensive review by the faculty
readers before they are approved. Thus the ADA is implying that the
Harvard professors who signed off on the dissertation may not have been
on the ball.  Elise Bassin received her PhD based on this dissertation.
If it didn't have merit, she wouldn't have received her degree.  Also
the Wall Street Journal reporter has a science degree, knows science
very well and taught at New York University's Science and Environmental
Reporting Program for a stint. She already checked the viability of
Bassin's dissertation with objective outside sources w ho said the
paper is publishable. And, I guess, the ADA also wants you to ignore
this quote,  "She did great shoe-leather epidemiology,"
says William Maas, head of oral health at the CDC and a supporter of
fluoridation)

The student notes in her thesis that there are several limitations to
her study and recommends that the findings be confirmed using data from
other studies. For example, she notes that the study may not accurately
reflect the actual amount of fluoride consumed by study subjects.

(Show us any studies that support water fluoridation which reflect the
amount of fluoride consumed by study subjects. This is a huge flaw, we
always point out,  in the studies the ADA uses to support its theory
that fluoridation safety reduces tooth decay. Interesting the ADA uses
the argument when they think it works for them)

The vast majority of studies by nationally recognized researchers in
widely-published, respected and peer-reviewed scientific journals
conclude that water fluoridation has not shown any ill effects on
health.

(The truth is that both a U.S. government panel and British scientists
found fluoridation proponent studies flawed and scientifically invalid)

Studies show that water fluoridation can prevent between 15-40 percent
of tooth decay, and that there is no association between cancer rates
in humans and optimal levels of fluoride in drinking water.

(Also not true - the New Jersey Department of Health reports higher
rate of osteosarcoma in fluoridated portions of New Jersey.  The
National Toxicology Program found more osteosarcoma in fluoridated
rats. Procter & Gamble reports a link between fluoride and cancer.
Drs. Burk and Yiamouyiannis found a higher rate of cancer in
fluoridated communities, even after adjusting for age, sex and race.
When fluoridation proponents were put on the witness stand in courts of
law, Drs. Burk and Yiamouyianns's cancer studies could not be refuted
scientifically. But cancer isn't the only health problem laid at
fluoridation's door)

The Centers for Disease Control and Prevention has proclaimed community
water fluoridation one of the 10 greatest public health achievements of
the 20th century.

(Notice they didn't say tooth decay reduction was the achievement. Yes
organized dentistry has been very successful in spreading around
fluoridation for the last 60 years to 2/3 of Americans via their water
supply and 100% via the food supply; but the U.S. Surgeon General
reports tooth decay is a national epidemic.)

According to our current Surgeon General, fluoridation is the single
most effective public health measure to prevent tooth decay and to
improve oral health for a lifetime, for both children and adults.

(Tooth decay has gone down over the years equally in fluoridated and
non-fluoridated countires.  There's no evidence that proves fluoride in
any form is responsible for the drop in tooth decay. Health generally
has improved markedly during the same time that decay rates declined)

Unless and until the weight of scientific evidence shifts to the
contrary, the American Dental Association continues to recommend that
community water supplies be fluoridated to reduce the risk of tooth
decay.

(This is sad because scientists are denied federal grant money to study
the ill health effects of fluoride.  Those that do manage to get grants
and show ill effects get fired and see no more research money, such as
Phyllis Mullenix who found and published a study showing fluoride
enters the brain and adversely affects behavior. Self survival steers
scientists away from even looking into this subject.   What the ADA is
telling you is  that the ADA's stack of invalid science is still higher
than the valid science showing fluoridations' harm - so the ADA wins.
That's not scientific.)

As a dentist, my goal is to help protect and improve your oral health.
I believe that water fluoridation is important in preventing tooth
decay.

(Yes they "believe." The science doesn't support this belief.)

As a member of the American Dental Association, I will be kept up to
date on the latest dental research, so if the science on this issue
changes, I will certainly let you know immediately.

(I've already shown you that the ADA will lie to it's members. The only
reason, dentists now were made aware of the bone cancer link is because
the media has picked up on it. So the ADA's number one goal is to
protect the image of  fluoridation and, therefore, their own image)

As the leader of a science-based profession, the ADA is open to new
scientific information and welcomes the opportunity to address it
according to the standards that prevail in the scientific community.

(The ADA is just a union that represents the best interest of dentists
- not the American public.  We would like a discussion not only on the
merits of the Bassin dissertation; but the merits of the studies which
show fluoridation is safe and effective and saves money, because
actually it's does none of those things)

    Wow, Paul--you must really be plugged into the ADA--I've been a member
for 30 years, but I never received that e-mail--thanks a bunch for
forwarding it!
