1. Premarin & Provera increase Breast Cancer risk

In 1995, the Nurses’ Health Study (one of the largest studies done to date), women taking synthetic estrogen alone had a 36% increase in risk of breast cancer; those on synthetic estrogen plus progestin had a 50% increase; those on progestins alone had a 240% increase of breast cancer. Women who, at the time of the study, had been taking estrogen and progestin for 5-10 years had a 45% increase in their risk of breast cancer.

2. Estriol is the protective estrogen, but most doctors use estradiol

The estrogen, “estriol” is completely missing from some forms of conventional hormone replacement therapy (HRT). In the female human body, estriol is the estrogen that is found in the greatest amount compared to estrone and estradiol. Over 80% of this natural triestrogen is estriol in females. Studies have shown that estriol protects the body from the more carcinogenic estrone and estradiol and is especially protective against breast cancer. Yet doctors continue to prescribe estradiol for HRT.

3. Breast Cancer spreads rapidly, but can be slowed & stopped!

Compare Prostate versus Breast cancer. Prostate cancer doubles in 5 years. Breast cancer can double in 3 months. Slowing the proliferation rate slows the cancer! Estrogen increases the proliferation rate, but progesterone decreases the proliferation rate considerably. A 1995 study by Dr. K. J. Chang indicated that unopposed estrogen increased cell proliferation by 230% whereas natural progesterone decreased it by more than 400%.

Note: . Normal breast cells often respond to E2 with accelerated growth resulting in dense, lumpy breasts with fibrocystic changes

4. Estrogen Dominance from environmental xenoestrogens can lead to Breast Cancer

Asians have a lower incidence of breast cancer, not because of soy, but because of fewer hormones and less estrogens in the environment. Besides Asia, incidence rates are also low in India, Gambia, and Israel. The low incidence rate of breast cancer is primarily in countries that are non-industrialized or less industrialized.

5. Natural Progesterone may shut down cancer replication

When breast cancer researcher Dr. David Zava studied the estrogen and progesterone levels in breast tissue specimens taken from women who had undergone surgery for breast cancer, he found that almost universally they revealed estrogen dominance and a deficiency in progesterone.

In studies by Dr. David Zava and Dr. K. J. Chang, samples of tumors were examined from women who were taking progesterone. Even though the tumors were described as malignant, the majority of the cells in the tumor were WELL DIFFERENTIATED & QUIESCENT (not replicating) in the women taking progesterone.

A link has also been established between cancer and progesterone on the genetic level. Researchers grew cultures of cancer cells and then treated them with estrogen and progesterone. They found that estrogen alone promoted cancer growth, but when progesterone was added, tumor suppressor genes were stimulated and the cancer growth was stopped.

6. The estradiol “patch” contains a potent form of estrogen

The “patch” contains 100% estradiol, which is the most potent of all the estrogens found in the female body; it contains no estrone and no estriol. A second study by Dr. William Hrushesky in Albany, New York revealed that estrogen promotes delayed apoptosis. Apoptosis is the system our body uses to destroy old cells. Normal cells are programmed to live for only a specified time and then die as new cells replace them. If old cells are not destroyed, it increases their risk of becoming cancerous. Natural progesterone was found to decrease delayed apoptosis.

7. Natural progesterone protects your breasts

A study at Johns Hopkins showed that the incidence of breast cancer was 5.4 times greater in women with low progesterone than in women who had good progesterone levels.

8. Birth Control Pills greatly increase breast cancer risk

According to Dr. John Lee’s book “What Your Doctor May Not Tell You About Breast Cancer”, teens taking birth control pills increases breast cancer risk by 300%.

“ When teenage girls take birth control pills, it increases their risk of breast cancer. It has been well established that when girls between the ages of 13 and 18- and to a lesser but still significant effect, women up to the age of 21 – use birth control pills, their risk of breast cancer can increase by as much as 600%. The younger a girl begins to use contraceptive hormones, the greater her risk of breast cancer. Because girls are reaching maturity much earlier today than even 10 or 20 years ago, and are more freely using contraceptive hormones, we have to ask whether this scenario is going to lead to a significant increase in breast cancer, particularly premenopausal breast cancer – which tends to be more aggressive”

Dr. Lee goes on to write that synthetic estrogens and synthetic progestins in birth control pills do NOT allow breast cells to mature. Instead the birth control pills stop breast tissue maturation, and these immature breast cells are more vulnerable to cancer causing chemicals later in life.

9. You should treat any breast injury with natural progesterone

Injury to the breast can cause cellular damage. Dr. John Lee MD, suggests that following any injury to the breast, a woman should put progesterone cream directly on that breast for at least 3 months

10. Natural progesterone, in the correct strength to protect the breasts, can be purchased without a doctor’s prescription!

Look for a natural progesterone crème containing 960-1000 mg. of USP Progesterone in a 2 ounce jar. You need USP progesterone, not just “wild yam”. Stay away from creams that contain any other hormones like DHEA. If you are menopausal and having hot flashes and night sweats and have no personal history of breast cancer or fibrocystic breasts, a crème containing red clover would be a good choice. If you have breast cancer or fibrocystic breasts, choose progesterone only. If you are still menstruating, choose progesterone only.
