ionizing radiation in the United States."

"Study links dental X-rays to brain tumor risk"
By Jennifer LaRue Huget
April 10, 2012
A study published Tuesday in the American Cancer Society journal
Cancer reported a link between certain kinds of dental X-rays and the
most common brain tumor, one that is almost always benign but can
still be debilitating.
The study found at a general level that people with meningioma were
more than twice as likely as people without the brain tumor to have
had a bitewing X-ray sometime in their life. For a bitewing X-ray, the
patient holds the film in place by biting down on a tab.
The exposures to dental X-rays in the study took place in the 1960s,
when dental X-rays delivered higher doses of radiation than today’s
do. The study compared the self-reported dental X-ray histories of
1,433 adults who had been diagnosed with the tumor with 1,350 who had
not.
The study also found an association between the less commonly used
panorex X-rays, which are taken outside the mouth and deliver a
panoramic view of the full set of top and bottom teeth, and meningioma
risk.
People who reported having had a panorex exam before they turned 10
were 4.9 times as likely to develop meningioma as those who had them
at any other time, and those who had had them most frequently (but not
necessarily at that young age) were about three times as likely to do
so as those who had never had a panorex exam.
The study reports that ionizing radiation is the major environmental
risk factor for meningioma and that dental X-rays are the most common
artificial source of exposure to ionizing radiation in the United
States.
Lead author Elizabeth Claus, professor at the Yale School of Public
Health and a neurosurgeon at Brigham and Women’s Hospital in Boston,
noted that risk factors for meningioma, the most commonly diagnosed
form of brain tumor, remain poorly understood, in part because
meningioma was only added to brain tumor registries in the United
States in 2004.
She added that it generally takes 20 to 30 years after exposure to an
environmental trigger such as radiation for meningioma to develop.
The tumor can reach sizes larger than a baseball and can cause
headaches, vision problems and loss of speech and motor control.
The American Dental Association recommends that dentists be judicious
in their use of X-rays. For patients whose teeth are healthy and who
are not at increased risk of developing cavities, the ADA suggests
children have X-rays about every one to two years; adolescents, every
year and a half to three years; and adults, every two to three years.
In a statement, the ADA noted the study’s potential flaws and
encouraged further research: “[T]he results rely on the individuals’
memories of having dental x-rays taken years earlier. Studies have
shown that the ability to recall information is often imperfect. . . .
Also, the study acknowledges that some of the subjects received dental
x-rays decades ago when radiation exposure was greater. Radiation
rates were higher in the past due to the use of old x-ray technology
and slower speed film.”
Claus said she does not want the research to send an alarmist message.
“Don’t panic,” she said, “and don’t not go to the dentist. But do look
into the guidelines and talk with your dentist.”
“It’s worth having that conversation,” she added.

My mother and three sisters all died of cancer. Tits and anus.
But you know, it's not too bad until about three weeks before the
patient croaks. About then, they really begin to stink, and pus and
stuff oozes out their holes and their skin starts dropping off.
Of course, within a week or so of death, their bowels give up the most
overpowering odor you can imagine.
I gave up visits about then. Whew!
But I still wonder, if in the afterlife -- if there is one -- these
departed look and smell as they did when they died. If so, I don't
want no part of that!

Possibly, I am not keen on them myself. What is really scary is the asbestos
sheeting I have found around my allotment, Asbetos is apparantly even worse
than plutonium and the black death combined with BSE.
Eke Zeke is not long for this world.

Two Uncles and an Aunt died of the big C all within a year of each other
:( My mum survived cervical cancer only to die of something else. That is
the way it happens.
My bowels never smelt sweeter and you beseech yourself in them if you doubt
the truth of that. I smell a troll.
Eke it's Zeke, who if he has inherited his dad's lifespan has about 15
months left.
