In September, a
large-sample, long-term Canadian study proved that an annual mammogram
was no more effective in preventing deaths from breast cancer than
periodic physical examinations for women in their 50s.
The study was
co-authored by Cornelia Baines, a professor of public health sciences at
the
University of Toronto and appeared in the Journal of the National Cancer
Institute. In the study of almost 40,000 women ages 50 to 59, half
received periodic breast examinations alone and half received breast
examinations plus mammograms. All learned to examine their own breasts
as well.
By 1993, 13 years
after the study began, there were 610 cases of invasive breast cancer
and 105 deaths in the women who received only breast examinations,
compared with 622 invasive breast cancers and 107 deaths in those who
received breast examinations and mammograms. "They found smaller
cancers, but ultimately the mortality rate was the same,ıı said Suzanne
Fletcher, a professor of preventive medicine at
Harvard Medical
School. She added that cancer screening programs are built on the
assumption that "finding it earlier is finding it better. . . . This
study questions that assumption."
In fact, truly early
detection would be better, but
by the time a tumor
has grown to a sufficient size to be detectable by either a mammogram or
a physical examination, it has been growing for several years, and
achieved more than 25 doublings of the malignant cell colony.
As Alternative
Medicine has maintained for years,
mammograms do far more harm than good.
Their ionizing radiation mutates cells, and the mechanical pressure can
spread cells that are already malignant (as can biopsies). In 1995 the
British medical journal The Lancet reported that,
since mammographic screening was
introduced in 1983, the incidence of ductal carcinoma in situ (DCIS),
which represents
12%
of all breast cancer cases, has increased by
328%,
and
200%
of this increase is due to the use of mammography.
This increase is for all women: Since the inception of widespread
mammographic screening, the increase for women under the age of 40 has
gone up over 3000%.
Mammogram
interpretation is often wrong. In 1996, the journal Archives of Internal
Medicine published results of a test of 108 radiologists throughout the
United
States. The test used a set of 79 mammograms where the diagnosis had
been verified by subsequent biopsies, surgeries or other follow-up. The
radiologists missed cancer in 21% of the films, thought 10% of the women
with no breast disease had cancer and thought 42% of benign lesions were
cancerous.
Further,
mammograms are not
diagnostic and too frequently lead to unnecessary breast biopsies, which
are an expensive, invasive surgical procedure that causes extreme
anxiety, some pain and often physical harm to many women who do not have
cancer.
According to the 1998
edition of the Merck Manual, for every case of breast cancer diagnosed
each year, from 5 to 10 women will needlessly undergo a painful breast
biopsy. Statistically, this means that any woman who has annual
mammograms for 10 years has at least a 50% chance of having at least one
biopsy -- even if she never develops breast cancer.
Why, then, does
mainstream medicine keep recommending mammograms? Do the math: a $100
mammogram for all 62 million
U.S. women over 40, and a $1,000+
biopsy for 1-to 2-million women, is an $8 billion per year industry.
There is a superior alternative: advanced thermography, which does not
use mechanical pressure or ionizing radiation, and which can detect
signs of breast cancer years earlier than either mammography or a
physical exam.
Mammography cannot
detect a tumor until after it has been growing for years and reaches a
certain size. Thermography is able to detect the possibility of breast
cancer much earlier, because it can image the early stages of
angiogenesis. Angiogenesis is the formation of a direct supply of blood
to cancer cells, which is a necessary step before they can grow into
tumors of size.
Thermographic breast screening is brilliantly simple.
Thermography measures the radiation of infrared heat from our body and
translates this information into anatomical images. Our normal blood
circulation is under the control of our autonomic nervous system, which
governs our body functions without our conscious will.
To screen for breast
cancer, a thermographer blows cool air over a womanıs breasts. In
response, our autonomic nervous system reduces the amount of blood going
to the breast, as a temperature-regulating measure. However, the pool of
blood and primitive blood vessels that cancer cells create is not under
autonomic control and is unaffected by the cool air. It will therefore
stand out clearly on the thermographic image as a "hot spot."
DR. MERCOLA'S COMMENT:
Earlier this month I reviewed a study from the National Cancer Institute
which showed that mammograms don't work to reduce the risk of death from
breast cancer. Their analysis confirms what we have suspected for some
time: that mammograms are not a good idea. Most physicians recommend
them for fear of being sued by a woman who developed breast cancer in
which he did not advise to get one. Now natural medicine physicians can
rest comfortably and encourage women to get a thorough breast
examination for abnormalities, as well as performing frequent
self-examinations.
Thermography, along with regular breast self-exams, does seem to be a
reasonable alternative to screen for this prevalent form of cancer among
women.
