In fact women in the Untied States produce more estrogen than third world women. Breast Cancer, as well as other cancers, are best treated preventatively. It is far easier to prevent them in the first place than to fight them later on. Studies have directly linked Estrogen Dominance to cancers in women. This is not good with cancer cells.
Progesterone inhibits the proliferation in favor of cell maturation.
Thus progesterone causes the cancer to stop multiplying and is a natural preventor of cancer. It would seem only wise to supply estrogen dominant women with natural progesterone. This should begin in the 10 to 15 years before menopause when estrogen dominance is so common.
