To Prevent Breast Cancer, Don’t Block Estrogen, Remove Iron!

Breast cancer prevention- use of rice bran extract to remove iron likely to be more effective than blocking estrogen

The idea of using strong anti-estrogen drugs to prevent or treat breast cancer should be challenged and replaced with natural methods of controlling or removing iron, says health journalist Bill Sardi.

Harsh anti-estrogens like Tamoxifen only leave women to deal with serious drug after effects of mental depression, calcifications and bone loss. Few women have heard that the local production of estrogen in fat cells in breast tissue release iron that tumors cells require for growth. By chelating (removing) iron rather than blocking estrogen, tumors should theoretically shrink without the undesirable side effects experienced with anti-estrogen drugs, says Sardi. This has actually been demonstrated in animal studies.

If estrogens alone were the primary factor in breast cancer, then why don’t more women get this form of cancer during their fertile years when hormone levels are very high? The answer to this question, says Sardi, is that monthly menstrual flow removed excess iron from the body. It should not be a surprise that precisely when women lose their ability to control iron, when monthly blood loss with accompanying iron depletion ceases, is exactly when the risk of breast cancer rises dramatically.

Most women are used to being short of iron, with nearly a third of women being anemic during the fertile years. The idea of too much iron, or iron being released in breast tissue, is not commonly reported. In animal experiments, high amounts of dietary iron do not induce tumors, but iron plus estrogen does increase cancer risk. Red meat and alcohol are dietary risk factors for breast cancer, and these foods increase the absorption of iron.

Cancer researchers are searching for iron removal drugs to treat cancer while natural iron chelators, for example those found in cereal bran, go unused and have no toxicity. Rice bran, flaxseed meal and sesame seed contain an iron-binding molecule (called phytic acid, or IP6). Extracts of rice bran (IP6), widely available in health food stores, have been shown to inhibit breast tumors in laboratory experiments.
