The Mammogram Debate
Learn the startling facts about this common but controversial procedure
By Joel Fuhrman, M.D.
The story of Jane Silverstein
is all too common. At age
thirty-seven, Jane went for
her first mammogram. Because of
suspicious findings, she was asked
to return the next day for a repeat
mammogram and ultrasound. By
the time these were completed, she
was trembling.
The following day, Jane was advised
to make an appointment to
see a breast surgeon for an excisional
biopsy. She had to wait two
weeks for the appointment with the
surgeon and then another week for
the surgery. During this entire period,
she worried so much about
breast cancer and the possibility
that her children might be left without
a mother that she slept poorly
and suffered anxiety.Her family physician
put her on anti-anxiety medications,
which helped somewhat,
but left her feeling “drugged” and
uncomfortable.
Fortunately,the breast surgery had
no complications, the biopsy was
negative, and Jane was told she was
“fine.” Fine, except now she is on
Paxil and Xanax for the anxiety she
suffered. Hopefully, she eventually
will recover and be able to be
weaned off the medications.
Did Jane make a good decision?
Disturbing facts
Breast cancer is the second leading
cause of death in North American
women. (Heart disease is number
one.) In spite of modern cancer detection
and treatment methods, the
percentage of women dying from
this common cancer has not changed
much in the last thirty years.1 As
the use of mammograms increased
markedly in this time frame, the
percentage of women dying of
breast cancer has remained remarkably
stable.
A campaign of fear
More than a decade ago, the American
Cancer Society recommended
that women get a baseline mammogram
at age thirty-five, followed by
annual screenings beginning at age
forty. The campaign to position
mammograms as the key weapon in
the fight against breast cancer was
initiated by the American Cancer Society,
with a number of medical
groups joining the fray. Instilling fear
about breast cancer was a campaign
strategy. To achieve this, the American
Cancer Society used greatly
exaggerated numbers and faulty
math to overstate breast cancer risk.
They admitted they did this—and
continue to do it—to promote mammograms.
They still trumpet the
claim that women face a one-in-eight
chance of developing breast cancer
during their lifetimes.
Where does this one-in-eight figure
come from? It is a cumulative
probability derived from adding up
all the chances a woman has of
developing breast cancer between
birth and age 110. Since women do
not generally live that long, this figure is not based on reality. More
sophisticated risk assessment gives
the actual risk of being diagnosed
with breast cancer before age sixty
as about one in 500. Even women
in their eighties do not face a one in
eight chance of developing
breast cancer. For example, at the
age of seventy, the risk of developing
breast cancer during the next
ten years is one in twenty-three. In
their zeal to help women, the
American Cancer Society and other
groups have created an epidemic of
fear.Unfortunately, that fear has not
been used to direct women to prevent
breast cancer—by avoiding
the causes of breast cancer. Rather,
it has been used to convince
women to think that using mammograms
to find cancer after it
already has developed is their best
hope for survival.
Multibillion dollar industry
Mammograms have been positioned
as the centerpiece of women’s
health care, and they are the most
prevalent “medicine” delivered to
our female population. Women
shuffle from their doctors to radiologists
and back, and if their mammograms
show abnormalities, they
are transferred to surgeons for needle
biopsies and excisional biopsies.
Today’s woman goes to doctors
to get yearly mammograms and
breast exams with little thought
given to the medical literature on
these subjects and the shocking
facts it reveals. Suffice to say, gynecologists
whose practices revolve
around giving postmenopausal women
estrogen replacement therapy
(a disproved and dangerous practice)
and ordering mammograms
will have little left to do if women
become better informed about the
risks associated with mammograms.
Mammograms help detect breast
cancer, and they help detect it earlier
than other diagnostic tools. But
in the process, they cause a lot of
fear and result in countless unnecessary
breast biopsies. In order to
uncover cancer and not give false
reassurance, radiologists are forced
to advise biopsies even when the
findings suggest the chance of cancer
is small. More than 80 percent
of all breast biopsies are negative
for cancer. In addition, these mammograms
with false positive results
(sent for biopsy and then found to
be negative) occur most frequently
in the forty to fifty age range. By the
time a woman has nine mammograms
between the ages of forty
and forty-nine, her chance of having
a false positive result that requires
her to have a biopsy is 43 percent.
Nearly half of all women getting
mammograms are eventually sent
for biopsies to evaluate “suspicious”
findings. When a woman with risk
factors (such as a family history of
breast cancer) gets nine or ten
mammograms between ages thirtyfive
and fifty, her chance of the radiologist
finding something suspicious
and sending her to get a biopsy
that returns negative for cancer
rises to 98 percent.
The problems caused by false
positives and unnecessary biopsies
might be acceptable if the increased
use of mammograms saved
women’s lives. But it does not
appear from the statistics that many
lives are being saved by this so called
“early detection.”
Between 1970 and 1990, as more
and more women got mammograms
at the urging of the medical
profession and health authorities,
breast cancer rates rose 24 percent.
As expected, more cancers were
being detected, and they were
being detected “earlier.” Five- and
ten-year survival rates improved,
and it appeared that women were
living longer with their cancers. But
those figures were misleading.
Sadly, the exact same percentage of
the same age as they did prior to
the widespread use of mammograms.
(See chart on p.3.) Increased
use of mammography has accomplished
little more than giving an
increasing number of women the
painful knowledge that they have
breast cancer.
Myth of “early detection”
Mammograms never detect “early”
breast cancer. By the time a cancer is visible to the human eye on a
mammogram, it is already teeming
with over a hundred billion cancer
cells—which have been there for at
least eight years—and it already has
had ample time to spread to other
parts of the body. In the majority of
cases, the cancer has spread outside
the breast, but the small groups
of cells that have traveled to other
parts of the body may be undetectable
for years.
Most breast cancers found on
mammograms, even the ones with
negative lymph nodes that appear
to be localized, will later be found
to have metastasized. Lumpectomy
for breast cancers that are thought
to be localized only stop the cancer
in a minority of cases, because in
most cases microscopic cancerous
cells already have left the breast.
Women with larger tumors or with
positive lymph nodes are treated
with radiation and then chemotherapy
in an attempt to destroy both
the localized cancer cells and those
that have migrated.
Mammograms enable us to treat
more patients who are found to
have breast cancer, but if the treatments
are not very effective, what
good is it to detect it earlier?
Chemotherapy for breast cancer still
should be considered experimental,
because the chemotherapeutic
agents used have a dismal track
record in producing long-term survival
of more than 15 years. Chemotherapy
has been shown to offer
some survival benefit in young (premenopausal)
women with breast
cancer, because the cancer is more
aggressive in that age range, but not
a significant increase in life expectancy
in older women.5,6 More
aggressive cancers are more sensitive to chemotherapy.
Mammograms done in the thirtyfive
to fifty age range—before
menopause—are even more controversial.
Many respected medical
authorities are clearly against mammograms
in this age group. First of
all, the risk of having breast cancer
before age fifty is about one in a
thousand. The dense breast tissue,
and the high incidence of benign
disease of the breast in young
women, leads to decreased accuracy
of mammograms.The chance of
having breast cancer in this age
group may be exceptionally low,
but the chance of having an abnormal
finding, necessitating further
views, ultrasounds, and repeated
tests and biopsies, is quite high.
In 1995, a meta-analysis of thirteen
studies found no evidence that
mammograms before age fifty saved
lives. That same study did show a
benefit for women over the age of
fifty. Researchers at the RAND
Corporation, a think tank in California,
performed a cost/benefit
analysis and did not recommend
women below age fifty receive
mammograms because—at a cost of
over 1.1 billion dollars annually
there was no evidence of benefit.
In January 1997, a National Institute
of Health consensus conference
was conducted to consider
whether or not screening mammography
reduces breast cancer
mortality among women aged forty
to forty-nine. The twelve-member
panel represented the fields of
oncology, radiology, gynecology,
geriatrics, and public health.Thirtytwo
experts presented scientific
data to the panel.The panel, working
with this data and with data in
the scientific literature, concluded
that mammography recommendation
for women in their forties was
not warranted.
Since this time, most researchers
reluctantly have been forced to
accept the consensus that mammograms
are not beneficial in this age
group. Many greeted this conclusion
with dismay and outrage.
Other groups, most notably the
American Cancer Society and the
American Medical Association, reaffirmed
their recommendations that even these younger women should
get annual mammograms. By contrast,
the Canadian Task Force on
Preventive Health Care, the American
Academy of Family Physicians,
and the American College of
Physicians do not recommend routine
mammograms in the age range
of thirty-five to fifty.
On the ship of false hope
Mammograms in all age groups are a
very poor screening tool. About 5
percent of mammograms are abnormal
or suspicious, and of these 80 to
93 percent are false positives that
cause unnecessary anxiety and further
procedures, including surgery. If
that were not enough to question
the reliability of mammograms as a
diagnostic tool, consider the unfounded
reassurance that results
from the false negatives that occur in
10 to 15 percent of women who
already have breast cancer that will
manifest clinically within one year.
In the October 2001 issue of The
Lancet, the Nordic Cochrane Centre
of Denmark published a follow-up
report on its groundbreaking 2000
analysis of the efficacy of screening
mammograms in reducing breast
cancer death. The new report confirmed
the earlier findings. After
reviewing the seven largest mammography
screening trials, no benefit
attributable to mammograms was
found for any age group. The new
research focused on the ability of
mammograms to reduce total mortality
because, as stated by the report’s
authors, this is the only “reliable”
measure of benefit.
The Danish researchers found
numerous flaws in the mammography
screening trials.They found that
the studies under review did not tally
fatal cases that were misclassified or
that were triggered by cancer treatment
such as radiotherapy.For example,
none of the leukemia deaths and
cardiac deaths occurring as a result
of chemotherapy for breast cancer
and none of the increased cases of
fatal lung cancer caused by radiation
to the breast during diagnosis and
treatment were ever considered in
prior studies. Lung cancer is a
known late-stage side effect to
breast cancer radiation, and congestive
heart failure is a known late
side effect of the cardiac toxicity of
chemotherapy. The Cochrane researchers
found that the studies’
claims that mammograms reduce
breast cancer deaths by 25 to 30
percent were invalid, since those
investigators did not consider all
other deaths related to breast cancer
treatments.
The researchers also found that
the studies that claimed to show
some benefit from mammograms for
women in their fifties and sixties
were 1) biased in favor of screening
and 2) incorrect because they only
looked at breast cancer mortality,not
all-cause mortality. Based on this
highly respected review, The Lancet
editors concluded,“There is no reliable
evidence from large randomized
trials to support screening mammography
at any age.”
The recent reassessment of the
2000 Cochrane analysis also confirmed
that breast cancer screening
with mammograms creates an overuse
of aggressive treatments. The
authors reasoned that the mammograms
detect lots of slow-growing
tumors that will never progress to
cancer within the patient’s lifetime
and classify these as cancer. These
account for the mammograms’ so called
“successes.” There are cellular
changes that may be histologically
cancerous but biologically benign.
Carcinoma-in-situ may be treated by
bilateral mastectomy even though
they do not progress to invasive disease ever. The flawed studies count
these as mammogram successes,
when they are not.At the same time,
the cancers that are truly invasive are
not really caught early enough to
make a difference. The patient only
appears to live longer because the
disease is diagnosed earlier. As stated
previously, the same percentage of
women are dying at the same ages
they were before the widespread use
of mammograms. The inescapable
conclusion drawn from these carefully
performed investigations is that
mammograms do not provide a survival
benefit in any age group.Those
who benefit are balanced out almost
equally by those who are hurt.
Facts vs. vested interests
The business of medicine is rarely
deterred by facts. The findings of
the Danish researchers did nothing
to change the position of the
American Cancer Society, The
American College of Radiology, and
the National Cancer Institute.These
institutions still support the discredited
notion that mammograms
“prevent” breast cancer. Mammograms
are entrenched in the practice
of conventional medicine.The
politics and economics within the
world of medical policy-making
govern the messages that are disseminated
to the public. The fact
is at best mammograms detect,
they do not prevent. To use the
word prevent in the same sentence
as mammograms is a tremendous
distortion of reality. The only
proven approach to prevention of
breast cancer is the adoption of
lifestyle modifications that help
stop cells from becoming cancerous
in the first place.
Controversies in the medical literature
rarely reach the public. In
the case of mammography, doctors
almost never admit to patients
that the benefits from mammograms,
if any, are marginal at
best. This does not mean that
some women will not be diagnosed
with breast cancer early
enough to have a curative lumpectomy.
For that woman, the mammogram
will have extended her
life. However, for every woman
whose life is extended, there are
almost an equal number who
would have lived longer had their
breast cancer not been discovered
and treated. For those women, the
medical treatments will shorten,
not lengthen their lives.
Cause or cure?
Unfortunately, mammography can
be the cause of a woman’s breast
cancer. When calculating its supposed
benefits, we need to include
in the equation the percentage of
women whose breast cancer was
promoted by the radiation exposure
from the mammograms themselves.
The younger you are when the
mammograms are performed, the
greater the risk of radiation-induced
cancer. According to Michael
Swift,M.D.,chief of medical genetics
at the University of North Carolina
at Chapel Hill, between 5,000 and
10,000 of the 180,000 cases of
breast cancer diagnosed each year
could be prevented if women’s
breasts were not exposed to radiation
from mammograms.Over a million
American women carry the
gene for ataxia-telangiectasia (A-T),
which makes them unusually sensitive
to the ionizing radiation in X
rays and five times more likely to
develop breast cancer.
The decision to screen for breast
cancer using mammograms should not be made lightly or based solely
on emotions. Intuition, hope, and
compassion can lead to the conclusion
that screening mammograms
should save the lives of young
women,and it is frustrating that science
has demonstrated otherwise.
Our desire to help a loved one by
“doing something about it” is
instinctive.When it comes to breast
cancer, the question is not whether
to do something or not, but rather
what to do about it. It is wrong to
instruct patients to depend on
mammograms, knowing that they
will inevitably undergo the anxiety
and frustration of repeated exams,
callbacks, biopsies, and unneeded
surgeries for nothing but a false
sense of security. As caregivers, we
need to tell our loved ones and all
women that there are proven steps
they can take to help prevent cancer
from ever developing in the
first place. (See Ten Ways to Help
Prevent Breast Cancer on p.5.)
All the misleading publicity
devoted to mammograms undercuts
the urgently needed efforts to
teach women that dietary and
lifestyle changes are their best
weapon in the fight against breast
cancer. Women are continually
urged by doctors, private and government
agencies, and the media to
undergo mammograms. How much
better it would be if the same
amount of effort would be put into
telling women that those who eat
four to five servings of vegetables
per day have a 46 percent lower
risk of breast cancer than those eating
only one to two servings per
day, and that women who eat six
fruits per day have a 35 percent
lower risk of breast cancer than
those eating fewer than two fruits
per day.
Ten Ways to Help Prevent Breast Cancer
Powerful steps you can take to protect yourself and your loved ones!
Overall, no one can disagree
with the fact that
mammograms do nothing
to prevent breast cancer and very
little to save women’s lives from
breast cancer. We just have not
seen this happen in the era of
extensive mammogram use. In
the meantime, don’t just sit back
and hope you don’t contract cancer.
Be proactive and adjust your
diet and lifestyle to achieve a high
level of health, so that any abnormal
cells never can overcome
your body’s powerful immune
defenses. Early, precancerous
changes in the breast can be normalized
by nutritional excellence.
Women can prevent breast cancer,
and even if they have cancer
they can significantly increase
their chances of survival with
nutritional excellence.
The best ways a woman can
protect herself from breast cancer
are as follows:
1. Do not drink alcohol.
2. Do not smoke.
3. Do not take estrogen.
4. Have babies and nurse
them for two years each.
5.Avoid dietary carcinogens,
which are predominantly found
in fatty fish and dairy fat.
6. Eat a high-nutrient, vegetable
based diet as described in
my book, Eat To Live. Green vegetables
are the most powerful
anti-breast cancer food. Take
note that a vegetarian diet does
not show protection against
breast cancer as much as a diet
rich in green vegetables, berries,
and seeds. It is the phytochemical
nutrient density and diversity
of the diet that offers the most
dramatic protection against cancer,
not merely the avoidance of
meat or fat.
7. Take a multivitamin to assure
nutritional completeness
and take at least 100mg of DHA
daily.
8.Use one tablespoon of
ground flax seeds daily.
9.Don’t grill or fry foods.
Steaming vegetables or making
vegetable soups should be the
major extent of cooking.
10. Exercise at least three hours
a week,and maintain a lean body
with little body fat.

Two Differing Positions Offered on Mammography
Dr. Fuhrman’s comments offer more hope for women than those of the U.S. Preventive Services Task Force.
The official U.S.government position
on mammograms offers little
hope to women. It states:
“The absolute probability of benefits
of regular mammography increases
along a continuum with age, whereas
the likelihood of harms from screening
(false-positive results and unnecessary
anxiety, biopsies, and cost)
diminishes from ages forty to seventy.
The balance of benefits and potential
harms, therefore, grows more favorable
as women age.The precise age at
which the potential benefits of mammography
justify the possible harms
is a subjective choice. The U.S. Preventive
Services Task Force did not
find sufficient evidence to specify the
optimal screening interval for women
aged forty to forty-nine.”
Dr. Fuhrman’s comments offer
more information and hope:
“Breast cancer is an emotionally
charged topic that gets a great deal of
media attention, and results of breast
cancer studies are often presented out
of context. Despite all of the research
that contraindicates the current widespread
use of mammography, doctors
tend to conform to the generally
accepted standard of care, no matter
what that standard is. Even doctors
“in the know” have no time to discuss
all the pros and cons of mammograms
with patients; they only have
time to write a prescription and move
on to the next patient. It is extremely rare to find a doctor who is well
informed and interested in practicing
true prevention—by making sure
their female patients exercise, don’t
drink alcohol, stay slim, and eat a
plant-based diet, loaded with high
nutrient vegetables.
“If you decide to have a mammogram,
keep in mind there is a good
chance an abnormality will be found
that will require further investigation.
By agreeing to undergo an initial
mammogram, you are accepting the
follow-up steps too. You have a good
possibility of needing multiple views,
repeat testing, needle aspirations, and
excisional biopsies to track down all
architectural distortions in the breast
that could potentially be cancer. The
medical profession’s intrusion in your
life can be extreme, and you can end
up living your life in fear. Perhaps
there is a better way.
“In the long run, if medical science
is going to help women by screening
for breast cancer, we need to find a
screening tool that detects precancerous
changes, so that something can be
done before the cancer occurs, along
the lines of what the Pap smear does
for cervical cancer.
“It matters little whether your doctor
thinks mammograms are effective,
or even if data in the future lends more
evidence to support the use of mammograms.
The benefits of detection can
never be substantial as long as we are
finding cancer at a stage when the
human eye has to see it on a film.
Instead, we need to devote our efforts,
money, and research into finding a
tool that really can find precancerous
changes in the breast and save lives. At
present, this is unlikely to happen
because of the billions invested in
mammogram equipment and the
huge investment in medical egos. Even
without a better screening tool, if the
millions of dollars currently spent trying
to coax women to get mammograms
were spent to educate and coax
women to breast-feed and avoid the
causes of cancer, we would save millions
of women’s lives.”
