Evidence of a Link to Cancer Featured Landmark Cover Story in NEWSWEEK, Feb. 5, 1990
Don't Drink the Water?
Brush your teeth, but the fluoride from your tap may not do much good - and may cause cancer!
Remember the great fluoride debate? Back in the 1950's, every voice of
authority, from the U.S. Public Health Service to the PTA, supported adding
fluoride to the water supply as an effective and totally safe way to promote
healthy teeth. The only opponents seemed to be John Birchers and other extremists
who regarded the scheme as a diabolical communist plot. In the years since,
most of the nation's major cities fluoridated their water, and the issue
appeared closed. No less an objective voice than Consumer Reports declared
in 1978, "The survival of this fake controversy . . . represents one
of the major triumphs of quackery over science in our generation."
In fact, the debate never ended. Now it may explode as never before,
posing new challenges to medical dogma and giving parents one more thing
to worry about. Government researchers have new evidence that casts doubt
on the benefits of fluoridation and suggests that it is not without risk.
The most incendiary results come from the National Toxicology Program (NTP),
which in 1977 was ordered by Congress to determine whether fluoride causes
cancer. This week NTP plans to release data showing that lab rats given
fluoridated water had a higher rate of a rare bone cancer called osteosarcoma.
According to a memo by the Environmental Protection Agency, "very preliminary
data from recent health studies . . . indicate that fluoride may be a carcinogen.
Fluoridation proponents are already criticizing the NTP study, but it
will be harder to discredit or ignore than the hundreds of earlier experiments,
of varying quality and from around the world, that have linked fluoride
to mottled teeth, skeletal damage, genetic defects and other ills. During
the two-year experiment, rats and mice drank water with different levels
of sodium fluoride. None of the animals drinking fluoride-free water developed
cancer, nor did any of those drinking water with the lowest fluoride concentration,
11 parts per million (ppm). But of the 50 male rats consuming 45-ppm water,
one developed osteosarcoma. Four of 80 male rats drinking 79-ppm fluoride
developed osteosarcoma. No mice or female rats showed signs of bone cancer.
Although the animals drank higher concentrations of fluoride than people,
(the legal standard is four ppm), such megadosing is standard toxicological
practice. It's the only way to detect an effect without using an impossibly
large number of test animals in lieu of the humans exposed to the substance.
Although the final NTP report will not be released for months, several
independent toxicologists find the results significant. Most important,
the rats who did not drink fluoride did not get cancer, indicating that
the malignancies are "not a fluke," says EPA scientist William
Marcus. There is also a convincing relationship between dose and response:
the more fluoride, the more cancers. Pathologist David Kaufman of the University
of North Carolina warns that the rat data must be examined to see if the
cancers appeared in the long bones of the arms and legs, as osteosarcomas
do in humans, or in other places, which might make the results less relevant
to people. Still, Kaufman says the NTP data "make fluoride look like
a weak carcinogen. It's obviously something to worry about" - but not
panic over. There are about 750 cases of osteosarcoma in the United States
annually; even if fluoride caused all of them - an impossibility - the lifetime
risk to any individual from drinking fluoridate tap water would still be
only about one in 5,000.
Too crude: If fluoride causes bone cancer in lab rats, then why, after
45 years of fluoridation, haven't researchers seen a rash of osteosarcomas
in fluoridated cities? Because epidemiology is too crude to detect it even
if the cancers are there. In the 1970's, the National Cancer Institute found
no sign of higher cancer rates in fluoridated cities. But that reassuring
finding may be misleading. According to Donald Taves, a fluoride expert,
if the difference were anything less than 7 percent it would not be detectable.
Another obstacle to definitive epidemiology is mobility: just because a
person got osteosarcoma in a fluoridated city does not mean he had been
living there all his life.
The NTP results assume an added importance when combined with recent
data on the shrinking benefits of fluoridation. According to the American
Dental Association (ADA), tooth decay is anywhere from 50 to 70 percent
less in fluoridated areas. But figures from the National Institute of Dental
Research (NIDR), part of the National Institutes of Health, suggest otherwise.
A 1987 survey of almost 40,000 schoolchildren found that tooth decay had
declined sharply everywhere. Children who always lived in fluoridated areas
had 18 percent less decay, compared with their peers who had lived in nonfluoridated
areas. This 18 percent translates into a difference of fewer than one cavity
per child. Similarly, in a 1986 paper in the British journal Nature, Australian
researcher Mark Diesendorf assessed 24 studies from eight countries and
found that cavity rates had declined equally in fluoridated and nonfluoridated
areas, suggesting fluoridated water isn't that important!
How can that be? "A good case can be made that it has to do with
fluoride in toothpaste and rinses," says dental-health-expert Brian
Burt of the University of Michigan. And even if drinking fluoridate water is slightly risky, there is no hint that fluoridated toothpaste - as long as you don't swallow any - is dangerous.
Tooth decay may also be declining because of better diet and hygiene. Also,
foods and beverages processed with fluoridated water are ubiquitous. (Many
bottled waters, though, do not have fluoride.) As a result, argues Alan
Gray, a leading pro-fluoridation dentist in Canada, "it's now becoming difficult
to provide accurate, ethical advice" about fluoridation.
Fluoridation is unique among environmental controversies, in that one
side has consistently denied that questions of risk or benefit even exist.
The ADA states, "Anti-fluoridation groups attempt to create the illusion
of a scientific controversy (which is ) merely a ploy to create doubt about
a well-researched, well-demonstrated preventive measure." But even
well-researched articles raise hackles. When, in 1988, Chemical & Engineering
News presented a balanced report on fluoridation, it attracted the wrath
of the medical establishment. Says Taves, "Too many scientists lost
their objectivity. This has become a religion on both sides."
Safe water: And that undercut the scientific process. The NIDR kept files
on people perceived as threats to fluoridation. Political decisions were
at odds with expert advice: a panel convened by the surgeon general in 1983
expressed concern, in closed sessions, about skeletal and dental damage
from fluoride. At one point, a member said, "You would have to have
rocks in your head, in my opinion, to allow your child much more than two
parts per million (fluoride)." Said another, "I think we all agree
on that." Even so, in 1986 EPA raised the fluoride standard from about
two ppm to four.
This month EPA opened a review of the standard. Once EPA receives the
official NTP report, it will establish a target "safe" fluoride
level. The Safe Drinking Water Act requires the level for carcinogens be
zero , but the standard may be based on what is technically feasible. Fluoridation
can be stopped immediately, but many communities with naturally fluoridated
water - up to 12 ppm - would have to remove it. As EPA wrestles with the
standard, John Sullivan of the American Water Works Association fears, "confusion
will reign": some local laws will still require fluoridation, a practice
many claim may cause cancer!
As they wait EPA's decision, pro-fluoridationists are invoking arguments
of social justice. Dental researcher Ernest Newbrun of the University of
California, San Francisco, contends that fluoridation promotes the health
of children of "all races and all socioeconomic classes," not
only those with enough money or discipline or access to the health system
to take a fluoride supplement every day. He and others say it is morally
wrong not to provide the benefits of fluoride. The NIDR's and other's surveys
suggest that fluoride in toothpastes and dental rinses also ensures healthy
teeth for those who use the fluoride products, they imply that those who
don't use them might suffer.
No one can foresee how the fluoride debate will play out this time. But
since the 1950's, the country's environmental consciousness has been heightened.
In the end, deciding whether or not to fluoridate turns less on science than on values. The sheer weight of good research may finally, after four decades, begin to inform those
judgements and even overwhelm the unscientific rhetoric that has characterized both sides of the debate for far too long.

Shocking Fluoride Facts
53% of the U.S. population drinks water containing fluoride, which
is costing taxpayers billions of dollars, not only for the fluoride, but
in added medical expenses!
41 of the 50 largest US cities have added fluoride to their drinking
water. Los Angeles and San Diego are two lucky ones, but Gov. Wilson is
trying to pass a fluoride bill for all California, which could bankrupt
cities and their medical facilities!
Millions of gallons of this deadly poison are doing untold damage.
If your area is fluoridated start action groups to stop this criminal action
now - to protect and save the lives of yourself, your family and future
generations!!!
Fluoride is a serious, long-term health Risk! Why take chances!!
