When was Thermography First Used to Investigate
Breast Cancer?
Digital Infrared Imaging was
first used to investigate breast cancer in 1957 by Dr. Raymond
Lawson, M.D., a surgeon and tumor metabolism researcher. Since
then, there have been over 800 peer-reviewed studies in medical
literature, studying over 300,000 women. In 1982, the FDA approved
thermography as a breast screening procedure. Over the past 30
years, there have been larger studies supporting its effectiveness,
as well as the development of strict, standardized protocols, and
technological advancements in imaging hardware and computer
processing.
Susan G. Komen Study
The Susan G. Komen Foundation funded a study released in May, 2007,
that essentially found that our increasingly polluted and toxic
environment is much to blame for the rise in cancer. As reported in
the press: [11]
More than 200 chemicals – many found in urban air and everyday
consumer products – cause breast cancer in animal tests, according
to a compilation of scientific reports published today.
Writing in a publication of the American Cancer Society, researchers
concluded that reducing exposure to the compounds could prevent many
women from developing the disease.
The research team from five institutions analyzed a growing body of
evidence linking environmental contaminants to breast cancer, the
leading killer of U.S. women in their late 30s to early 50s.
Experts say that family history and genes are responsible for a
small percentage of breast cancer cases but that environmental or
lifestyle factors such as diet are probably involved in the vast
majority.
In other words, environmental toxins continually pollute the body.
Our natural detoxification systems work less efficiently over time.
More free radicals are formed, damaging our DNA. The stage is set
for disease.
Thermography is a screening tool which can help raise suspicions of
breast cancer at an early stage, when there is still chance of
complete cure.
Mammography vs. Thermography
Researchers have long warned that the compressive force used to
obtain useable mammograms may be a contributing factor to breast
cancer:
The British standard for the force used to squeeze the breast as
flat as possible corresponds to placing twenty 1 kilogram bags of
sugar on each breast. Researchers [at the University of Aberdeen,
Scotland] fear that this force may be excessive and enough to
dislocate and spread any existing cancer cells. Animal experiments
have shown that the number of cancer sites can increase by as much
as 80% when tumors are manipulated mechanically. A recent study in
Malmo, Sweden found that the death rate from breast cancer among
women under 55 was 29% higher in a group which had been screened
with mammography than in the unscreened control group. [2]
There is mounting evidence that the x-rays from repeated mammograms
induce cancer. Dr. John W. Gofman, an authority on the health
effects of ionizing radiation, estimates that 75 percent of breast
cancer could be prevented by avoiding or minimizing exposure to the
ionizing radiation. This includes mammography, x-rays and other
medical and dental sources.
"Since a mammogram is basically an x-ray (radiation) of the breast,
I do not recommend mammograms to my patients for two reasons: 1) Few
radiologists are able to read mammogams correctly, therefore
limiting the procedure's effectiveness. Even the man who developed
this technique stated on national television that only about six
radiologists in the United States could read them correctly. 2) In
addition, each time the breasts are exposed to an x-ray, the risk of
breast cancer increases by 2 percent."
The August 2007 issue of Radiology bemoans the growing number of
mammography centers across the United States that are closing down.
Radiologists blame low reimbursement from the insurance companies
and a frightening degree of liability.
With mammograms, the false negative reading rates (not detecting
cancers) range from 10% to 40%.
According to the 2002 Breast Cancer Study, issued by the Physician
Insurers Association of America (PIAA), internists were named in 7%
of the surveyed failure-to-diagnose breast cancer suits brought
during the 1990s. Family physicians were named in 11% of cases and
gynecologists in 29%. Radiologists topped the list, however, being
named in 40% of all failure-to-diagnose breast cancer claims.
Fast Facts:
- In 1982, the FDA approved breast
thermography as an adjunct diagnostic breast cancer
screening procedure
- Of the extensive research conducted
since the late 1950's, well over 300,000 women have been
included as study participants
- The size of the studies are very
large: 10k, 37k, 60k, 85k
- Some studies have followed
participants up to 12 years
- Strict standardized interpretation
protocols have been established for 15 years to remedy
problems with early research.
- Breast thermography has an average
sensitivity and specificity of 95%
- An abnormal thermogram is 10 times
more significant as a future risk indicator for breast
cancer than a first order family history
- A persistent abnormal thermogram
carries with it a 22x higher risk of future breast cancer
- Extensive clinical trials have shown
that breast thermography significantly augments the long
term survival rates of its recipients by as much as 61%.
When used as a multimodal approach (clinical exam +mammography+thermography),
95% of early stage cancers will be detected.
