In this months issue of the Bowtech News we’ll be looking
into a drug
that has been full of controversy…….Tamoxifen.
We’ll also be looking at an alternative to this
And as usual a couple of famous quotes.
This drug is considered to be an anti-cancer drug. It may be
used to treat
breast cancer. It has been used in some cases in which cancer has
to other areas of the body. Its most effective use is with cancers that
on the presence of estrogen. It is also considered an estrogen blocker.
Estrogen blockers or antiestrogens work by blocking estrogen
tissue, and while estrogen may not cause the cancer, it may stimulate
Tamoxifen was initially developed to treat breast cancer in
stages and has been in use for more than 20 years. Tamoxifen is now
used to treat breast cancer as well as other types of cancer, such as DCIS
(ductal carcinoma in situ), following surgery and radiation.
Tamoxifen is also being prescribed by some doctors as a
measure for women with a high risk of breast cancer. In a 5 year
study of more
than 1,500 "high risk" women, tamoxifen cut the number
of cases by almost
45%. My question to this is, does this mean that
just because these
women were "high risk" that they
would have had breast cancer had
they not been involved in this study or taken

causing Drug Approved for Healthy Women
Cato the Elder, a Roman statesman that lived from 234–149 BC
recognized the possible anti-cancer activity of substances such as
said, "If a cancerous ulcer appears upon the breast, apply a
cabbage leaf and it will make it well."
The Life Extension Foundation has called this substance
persons substitute for tamoxifen."
Indole-3-Carbinol, or I3C is a phytochemical that is found in
vegetables such as broccoli, green cabbage, cauliflower, Brussel
turnips, kale, watercress, and mustard seed. Research on I3C dates back
1960’s, where it was being looked at for its actions with chemical
carcinogens. Since the 60’s, research with I3C has shown its capabilities in
regard to preventing and maybe even treating hormone related cancers.
studies have shown that this vegetable extract:
Increases the conversion of estradiol to
estrogen, and this has been shown to reduce
breast cancer incidence.
Works in estrogen receptor negative breast cancer cells.
Stops human cancer cells from growing (54-61%) and
provokes the cells to apoptosis (self destruction).
Inhibits MCF7 human breast cancer cells better than
tamoxifen under laboratory conditions.
Protects against the environmental toxin, dioxin.
Restores p21 tumor suppressor gene.
Provides antioxidant protection.
*20HE is considered to be a more favorable form
It is less active than estradiol, so when
it occupies the estrogen receptor, it
blocks estradiol’s strong "grow" signal.
In a 2 month study, 25 women were given I3C. Levels
estrogen declined as the weaker estrogen
increased. More importantly,
(an estrogen metabolite associated with breast and
endometrial cancer) fell.
I3C also helps to prevent cancer by blocking carcinogens.
Aflatoxin is a
cancer causing agent that comes from the mold on peanuts, corn,
other grains. Studies have been done on I3C and aflatoxin that show that
in the diet block aflatoxins effect in the liver, and stop it from causing
It is important that if you take I3C, not to be mislead into
taking one of its
derivatives such as DIM (diindolylmethane). DIM is one of the
chemicals that I3C converts to in the stomach. DIM is only one of dozens
of derivatives to come from I3C and the benefits of I3C come from a
of I3C derivatives, not any single factor.
Those who are hypersensitive to I3C or to any component of an
indole-3-carbinol – containing product.
Pregnant women and nursing mothers should avoid I3C
Those with cancer should seek their doctor’s advice before
supplement with I3C on their own.
Drugs: Antacids, H2 Blockers, Proton-pump inhibitors.
Tamoxifen: Indole-3-Carbinol may be synergistic with tamoxifen
protecting against breast cancer, but make sure you acquaint yourself
much information as you can about tamoxifen before submitting
to taking this
drug. Make an informed decision.
