Dairy Consumption and Breast Cancer
Note: Below
you will see references to "IGF-1". To better understand
its role in cancer in general and breast cancer specifically, you
need to read the following...
-------------------------------------------------------------------------------------------------------
There is only
one hormone that is identical between any two species. That powerful
growth hormone is insulin-like growth factor, or IGF-I. IGF-I
is identical in human and cow. IGF-I survives digestion and has
been identified as the key factor in breast cancer's growth.
When breast
feeding, lactoferrins and immunoglobulins are protected from digestion
(which benefits the nursing infant); mamillian milk is a hormonal
delivery system. By drinking cow's milk, IGF-I is delivered in a
bioactive form to the body's cells. When IGF-I from cow's milk alights
upon an existing cancer, it's like pouring gasoline on a fire.
Scientists have
found that the IGF-I system is widely involved in human carcinogenesis.
A significant association between high circulating IGF-I concentrations
and an increased risk of lung, colon, prostate and pre-menopausal
breast cancer has been reported.
IGF-I has been
identified as a key factor in the growth of every human cancer.
Drink milk, and one doubles the amount of (free and unbound) IGF-I
in the human body. The nations with the highest rates of breast
cancer include Denmark, Norway, Holland, Sweden, closely followed
by the US. These nations also have the highest per-capita consumption
rates of milk and cheese. Coincidence?

Here's the Studies
"Human
Insulin-like growth factor (IGF-I) and bovine IGF-I are identical.
Both contain 70 amino acids in the identical sequence." --
Judith C. Juskevich and C. Greg Guyer. SCIENCE, vol. 249. August
24, 1990.
"Insulin-like
growth factor (IGF)-I can affect the proliferation of breast epithelial
cells, and is thought to have a role in breast cancer." --
The Lancet, vol. 351. May 9, 1998
"The insulin-like
growth factor (IGF) system is widely involved in human carcinogenesis.
A significant association between high circulating IGF-I concentrations
and an increased risk of lung, colon, prostate and pre- menopausal
breast cancer has recently been reported. Lowering plasma IGF-I
may thus represent an attractive strategy to be pursued..."
-- Int J Cancer, 2000 Aug, 87:4, 601-5
"...serum
IGF-I levels increased significantly in the milk drinking group
an
increase of about 10% above baseline-but was unchanged in the control
group." -- Journal of the American Dietetic Association, vol.
99, no. 10. October 1999
"IGF-I
is critically involved in the aberrant growth of human breast cancer
cells." -- M. Lippman. J. Natl. Inst. Health Res., 1991, 3.
"IGF-I
has been identified as a key factor in breast cancer." -- Hankinson.
The Lancet, vol. 351. May 9, 1998
"Estrogen
regulation of IGF-I in breast cancer cells would support the hypothesis
that IGF-I has a regulatory function in breast cancer." --
A.V. Lee, Mol-Cell- Endocrinol., March, 99(2).
"IGF-I
is a potent growth factor for cellular proliferation in the human
breast carcinoma cell line." -- J.C. Chen, J-Cell-Physiol.,
January, 1994, 158(1)
"Insulin-like
growth factors are key factors for breast cancer growth." --
J.A. Figueroa, J-Cell-Physiol., Nov., 1993, 157(2)
"IGF-I
produces a 10-fold increase in RNA levels of cancer cells. IGF-I
appears to be a critical component in cellular proliferation."
-- X.S. Li, Exp-Cell-Res., March, 1994, 211(1)
"IGF-I
plays a major role in human breast cancer cell growth." --
E.A. Musgrove, Eur-J-Cancer, 29A (16), 1993
"Positive
correlations between foods and cancer mortality rates were particularly
strong in the case of meats and milk for breast cancer, milk for
prostate and ovarian cancer, and meats for colon cancer." --
Rose DP, Cancer 1986 Dec 1;58(11):2363-71
"Breast
cancer rates are lower in populations that consume plant based diets."
- American Cancer Society Cancer Facts and Figures, 1994
"No dairy
products are hormone-free. There are literally dozens of hormones
in all fluid milk, including estrogen, somatotropins, prostaglandins,
and growth factors." -- Tom Helscher, director of industry
affairs for Monsanto (Estrogen? In her entire lifetime, a human
female naturally manufactures the equivalent of one-half tablespoon
of estrogen. Nano-molecular amounts (measured in billionths of a
gram) of this powerful steroid hormone define the essence of a woman.
Consumption of estrogen in milk and dairy products affect a woman's
emotions, physiology, and increase her chances of getting breast
cancer, uterine cancer, and ovarian cancer.)
When you combine
the above with milk's connection to diabetes and osteoporosis, do
you need more reasons to just say no to dairy products?
