Many women are under the impression that there is little they can do protect against breast cancer. This
is a fallacy… There is a plethora of clinical research on the protective benefits of food. All women are at
risk of getting breast cancer. And the longer you live, the bigger your risk. At age 25, your chance of
getting breast cancer is 1 out of 19,608. By age 40, your risk increases to 1 out of 217. As you celebrate
your 65th birthday your chance of getting breast cancer is 1 out of 17. And your overall risk? Assuming
you live to age 90, your risk of getting breast cancer is 1 out of 7.1
My mother should have lived to at least 90. She was a vibrant and exceptional woman who had been in
perfect health until she developed breast cancer at age 70. She had done all the “right” things -- yearly
mammograms and self breast exams. When her breast cancer spread leading to her death five years later,
she was robbed of 10 to 15 years of life. While we can't prevent these consequences of living to a ripe old
age, we can protect ourselves from much of the damage they cause.2 In this Ask the Doctor, we're going
to talk about breast cancer and how by reducing their risks women can protect themselves from this
deadly disease.
Q. It seems like everyone that I know has a
sister or a friend or a co-worker who has
breast cancer. Are there more breast cancer
cases than there used to be?
A. Yes there are, but in fairly specific ways.
That big generation of Baby Boomers continues
to influence the nation in ways they probably
never expected. Because the US population as
a whole is aging, the actual number of women
who are diagnosed and who die of breast
cancer each year has indeed grown. Most
breast cancers occur in women over the age of
50; the average age at diagnosis is 64. And in
2011, as Baby Boomer women (baby girls born
between 1946 through 1964) reach 65, the
number of breast cancer cases will also
continue to rise. 1
Besides age, other traditional breast cancer
risks include:
• Personal or family history of breast cancer
• Smoking
• Overweight or obesity
• Prolonged estrogen exposure
• First full-term pregnancy after age 30
• Never having a full-term pregnancy
• Heavy alcohol use
• Early start of menstruation
• Late menopause. 3
Research over the last decade has identified
many more:
• Eating red meat-especially well done
and grilled
• Eating sugar and refined carbohydrates
• Lack of exercise
• Not eating a diet high in fresh whole
organic fruits vegetables and whole grains
• Stress
• Environmental toxins
• Staying up late at night
• Certain pharmaceuticals, especially
Hormone Replacement Therapy 1-5
Q. How does just living my life put me at
risk of breast cancer?
A. The answer lies deep in our cells. Our body's
cells are the building blocks of organs (like the
heart, lungs, and brain), and tissues (such as
nerves, blood, and connective tissue). To keep
these tissues and organs strong, our cells divide
and reproduce, replacing worn out, sick, or
damaged cells with cells that are new and
healthy. This is an ongoing and dynamic process. 4
But as time goes by, some cells get larger and
less able to divide and reproduce as they should.
Cells start retaining harmful pigments and fatty
substances. Toxins and waste products in the
environment that we come into contact with
begin to accumulate, and so do injuries from
ultraviolet light and the by-products of
metabolism. Since we're continually exposed to
these hazards, our cells may start acting abnormally.4
All cancers begin from a single abnormal cell
that begins to grow out of control. While
normal cells divide only to replace worn-out or
dying cells and to repair injuries, cancer cells
grow and divide wildly. Instead of dying, they
outlive normal cells and continue to form more
abnormal cells. Although there are many kinds
of cancer, they all originate from the out-ofcontrol
growth of abnormal cells.4
Q. How can I protect my cells from
these hazards and keep them from
behaving abnormally? This all sounds
extremely complicated.
A. Well, you're right--all cancers, including
breast cancer, are highly complex diseases.
It's taken decades of dedicated research and
study to get us to where we are now in our
understanding of how cancer begins.
Even though cancers start as a single abnormal
cell, they are rarely, if ever, caused by a single
risk factor. We know that exposure to one risk
factor, may make us vulnerable to others.
We've discovered that some hazards are more
dangerous than others. We are learning more
and more every day about how certain nutrients
can provide powerful protection from cancer,
especially breast cancer.5,6 And we've also
recently determined that five very common
health hazards:
- Free radical formation
- Chronic inflammation
- Misguided immune responses
- Hormonal imbalance, and
- Exposure to toxins,
contribute significantly to the initiation and
growth of cancer, including breast cancer.4-6
But without a doubt, one of the most
exciting and encouraging findings to date is
that by simply adding seven nutrients to our
diet each day, we gain powerful protection from
breast cancer. Because these seven nutrients -
- Green tea
- Maitake mushrooms
- Grape seeds
- Turmeric
- Diindolylmethane, or DIM for short
- Vitamin D, and
- Calcium D-glucarate
are able to protect our cells from much of
the damage caused by the five common
breast cancer health hazards.
Q. How exactly do these nutrients prevent
or kill breast cancer cells?
A. Many of the seven nutrients work to
prevent breast cancer by eliminating excess
estrogen. While we need some estrogen to
keep us healthy, excess estrogen can cause
breast tumors to grow bigger, stronger, and
more deadly.2,3
One big reason why obesity is associated
with an increased risk of breast cancer is
because fat cells produce estrogen. After
menopause, fat becomes the primary site where estrogen is manufactured in our
bodies. Obviously, the more fat you have; the
more estrogen your body will produce.2,3,7
It is also a troubling fact of modern life that
we are continuously exposed to cancercausing
chemicals and toxins. These toxins
come in part from contaminants in the food
we eat and pollutants in the air we breathe.5,6
Many of the seven nutrients help our bodies
get rid of harmful toxins, while others block
their entrance.
While food as medicine is a pretty far-out
concept in modern medicine, it's the
backbone of traditional medicine - the type
of medicine utilized by more than 85% of the
world's population.8 Despite the fact that
these seven nutrients have long history as
protectors against breast cancer in traditional
medicine, most American women have either
never heard of them, or only know them by
name. That being the case, let's take a look
at each one:
Turmeric
Ounce for ounce, you can't find a more
breast cancer protective plant than turmeric
root. Its iridescent bright-orange pigment
has long been used as a natural food
coloring and spice; turmeric is one of the
principle ingredients in curry powder. While
turmeric is known more for its culinary
rather than health benefits, it's not for lack
of effort! Turmeric has almost an
embarrassment of riches-in the form of
powerful plant chemicals-to protect women
against breast cancer.9 Research has shown
that turmeric:
• blocks entry of breast cancer causing
toxins into the body
• inhibits breast cancer cell proliferation
• shuts off new blood vessel growth in
breast cancer tumors
• prevents tumors from invading into the
surrounding tissues
• causes apoptosis or cancer cell death
• inhibits over-expression of COX-2
enzymes in breast cancer cells
• increases the effectiveness of
chemotherapy and protects against
damaging side effects.10-13
Green tea
Women who drink green tea regularly have
significantly lower rates of breast cancer.
Japanese women who drink lots of green tea
have very low rates of the disease. And if
women who frequently drink green tea do
end up with breast cancer, they typically
have less aggressive tumors and a much
better prognosis.14
One of green tea's active ingredients
responsible for breast cancer inhibition is
epigallocatechin-3 gallate or EGCG. This allnatural
plant compound contains powerful
antioxidants and anti-inflammatories.15
Antioxidants protect us from naturally
occurring unstable by-products called free
radicals. Because they are missing at least
one unpaired electron, free radicals scavenge
and steal electrons from stable molecules.
Normally, our bodies can handle free radicals.
But too many can overwhelm our cells,
damaging their membranes and the genetic
material DNA.16
Inflammation is another natural and needed
bodily process. If you fall and sprain your
wrist, blood rushes to the injury causing the
immediate warmth, and swelling of
inflammation. The blood provides support
and brings nutrients to the damaged muscles;
once they have healed the extra blood supply
is no longer needed and the inflammation
goes away.17
Sometimes, however, inflammation occurs
without any evident injury. The body sends
blood to a joint or organ, mistakenly
believing damage has occurred at the site.
Because no injury has occurred, the
inflammation persists and causes destruction
of the surrounding tissues that provides
support and brings nutrients to damaged
muscles or infected tissues.17Inflammation
has also been shown to speed up the growth
of tumors and increase their ability to invade
into surrounding tissues. Green tea's EGCG
mops up excess free radicals and resolves
unneeded inflammation.15,18,19
Maitake Mushrooms
For thousands of years, maitake mushrooms
have been linked to good health in those
who eat them. Called “dancing mushrooms”
(possibly due to their wavy, rippling
appearance or possibly due to the little
dance of joy mushroom hunters perform
when they find them in the woods),
maitakes contain an important compound
called D-fraction.20 Not only does the
D-fraction in maitake mushrooms stop the
growth of breast cancer tumors, it also alerts
and stimulates powerful immune cells to
fight the disease. Maitake also inhibits the
metastasis, or spread, of breast cancer
elsewhere in the body.20-22
Because of this success, maitake is now being
used in clinical trials of women with breast
cancer. One study reported significant
improvement of symptoms, including
reduction of the tumor when maitake was given to breast cancer patients who were also
receiving standard chemotherapy.23
Grape Seed
Like all fruits, grapes are filled with super
healthy plant chemicals and compounds.
They're also very sweet and tasty and one of
the most popular fruits in the United States.
While seedless varieties might make grape
eating more appealing for some of us,
researchers have discovered that much of the
grape's goodness is actually contained in the
tiny seeds. The skins contain resveratrol
which is extremely protective as well.
Aromatase is an enzyme that helps make
estrogen. As we stated earlier, high levels of
estrogen are known to fuel breast cancer cell
growth. Some of the most promising
chemotherapy drugs are the new aromatase
inhibitors and inactivators - less aromatase,
less estrogen. And less estrogen means breast
cancer tumors that are unable to divide,
grow, spread, or progress.5,6
Researchers have found that grape seed
extract lowers aromatase levels, too -
though not as strongly as the synthetic
chemotherapy drugs.24-27However, cancer
researchers are so intrigued by grape seed
extract's ability to lower aromatase that
they are conducting a clinical trial to study
its effect in healthy, post menopausal
women at risk for breast cancer. They'll
take a grape seed extract supplement to see
how well it blocks estrogen production. And
the information they find may help
women everywhere.28
Diindolylmethane (known as DIM)
This powerful nutrient comes from broccoli -
the much disparaged green vegetable.
Diindolylmethane, or DIM for short, has a
direct effect on the hormone estrogen and
how it is metabolized. After estrogen
completes its desired activity, it returns to
the bloodstream to be broken down, or
metabolized, in the liver.7 Like all substances
that the liver metabolizes, estrogen is
broken down into “metabolites” through
certain pathways. Researchers have found
that estrogen can be broken down in two
enzymatic pathways in the liver, resulting in
two very different metabolites.29
One pathway, the 2-hydroxy pathway, results
in beneficial or “good” estrogen metabolites.
These “good” estrogen metabolites are
released into the bloodstream where they
account for many of the benefits of
estrogen, including the prevention of heart
disease and strong, healthy bones.29,30
Estrogen broken down in the “bad” estrogen
metabolism pathway - the 16-hydroxy
pathway - results in "bad" estrogen
metabolites that are linked to many health
problems, including breast cancer.29,30
DIM shifts the metabolism of estrogen from
the “bad” 16-hydroxy pathway to the “good”
2-hydroxy pathway and drastically reduces
our risk of breast cancer.30-34
Vitamin D
Most of us know that vitamin D is manufactured
in our skin when we're outside in the sun.
We probably also know that vitamin D is
needed for calcium absorption and is
essential in the formation of bones and
teeth. But vitamin D's ability to protect us
from cancer by preventing the overproduction
of cancer cells is a fairly new finding.35
Researchers at Birmingham University and
St. George's Hospital in England recently
discovered that breast tissue contains an
enzyme that activates vitamin D. Levels of
the enzyme are elevated in breast tumors -
suggesting the vitamin is produced to try to
combat the spread of cancer.36
Previously it was thought that the active
form of vitamin D - cholecalciferol, which is
a potent anti-cancer agent - was only made
in the kidney. The researchers think the
presence of cholecalciferol in breast tissue is
part of the breast's inborn natural immune
response to cancerous tumors.35-38
Calcium D-Glucarate
In the liver, excess estrogens and other
toxins are bound or attached to a chemical
called glucuronic acid. Once bound, estrogen
is deposited in the bile and ventually
eliminated in the stool.7
However, an enzyme called betaglucuronidase
can break this bond between
estrogen and glucuronic acid. When this
happens, estrogen is released from its bond,
capable of causing harm once more. Increased
beta-glucuronidase activity is associated with
an increased risk for various cancers,
particularly hormone-dependent cancers like
breast cancer.39
Fortunately, scientists have discovered that a
natural substance found in foods, calcium
D-glucarate or CDG can stop the activity of
beta glucuronidase. CDG keeps the harmful
estrogen bound to glucuronidase.40 While
CDG is found in fruits and vegetables, the
amounts may not be sufficient to maintain
effective levels to stop beta-glucuronidase.
CDG has been shown in experimental studies
to significantly stop breast cancer growth.39-41
Q. I know I can buy broccoli, grapes, and
green tea from the grocery store, but what
about the other nutrients?
A. Actually, the best way to take the
nutrients is in supplements. This is a much
more convenient method, too. That's because
if you wanted to get all of the benefits of
DIM from food, for example, you'd need to
eat two pounds of broccoli each day! And
getting the proper amount of grape seeds
would require eating several pounds of grapes
each and every day, as well.42
When shopping for the seven nutrients in
a supplement, be sure to look for
standardized nutrients and manufacturers
with good reputations.
Q. My sister-in-law has breast cancer and
when she hears information on prevention
and protection from the disease, she feels
responsible for developing the disease.
A. Your sister-in-law has nothing to feel
responsible about. She didn't ask for this.
She's done the very best she could. And so
did my mom! Women with breast cancer must
not use this information to beat themselves
up. They have much more important things
to do than needlessly ponder about past
events. What is important is to learn as much
as you can about ways to protect yourself
from breast cancer and start doing them now.
If you have breast cancer, these same
techniques--simple diet and lifestyle changes
and certain nutritional supplements--can
dramatically lower your chances of a
recurrence and improve your chances of
survival with some.
My book, Waking the Warrior Goddess: Dr.
Christine Horner's Program to Protect Against
& Fight Breast Cancer provides even more
information on how to fight and protect
against breast cancer.
One important last note. Please understand
that none of these seven nutrients has been
shown to cure breast cancer. Nutritional
supplements are simply that: supplements
to food, medication, and treatments. They
must not replace surgery, chemotherapy, or
radiation - or any other treatments for
breast cancer. The very best health outcomes
(like living a long healthy life) occur when
women work with their physicians to meet
the goals of treatment, including the defeat
of breast cancer!
