(NaturalNews) You've heard the good news about vitamin D for years: It's a "miracle" medicine that reduces cancer rates by 77% according to previous research (http://www.naturalnews.com/021892_c...). It also happens to be a powerful anti-cancer medicine that can both prevent and help reverse breast cancer.

Yet, bewilderingly, the cancer industry still refuses to teach women about vitamin D. Ever wonder why?

Today, we bring you a compilation of expert quotations on vitamin D and breast cancer, cited from some of the most authoritative books and authors in the world. Feel free to share what you learn here with others who may also be suffering from breast cancer.

Vitamin D and breast cancer

Sunlight triggers the formation of vitamin D in the skin, which can be activated in the liver and kidneys into a hormone with great activity. This activated form of vitamin D causes "cellular differentiation" - essentially the opposite of cancer. The following evidence indicates that vitamin D might have a protective role against breast cancer: Synthetic vitamin D-like molecules have prevented the equivalent of breast cancer in animals.

Two equally effective sources of vitamin D in humans are derived from plant ergosterol, which is converted to ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3) by the action of sunlight on the skin. The body uses vitamin D3 for normal immune system function, to control cellular growth, and to absorb calcium from the digestive tract. Vitamin D3 can inhibit the growth of malignant melanoma, breast cancer, leukemia, and mammary tumors in laboratory animals. Vitamin D3 can also inhibit angiogenesis, the growth of new blood vessels that permit the spread of cancer cells through the body.

There's surprising new evidence that older women who skimp on foods rich in vitamin D are more likely to develop breast cancer, according to Frank Garland, Ph.D., of the Department of Community and Family Medicine at the University of California at San Diego. This may also help explain fish's anticancer protection, because fatty fish is packed with vitamin D. Specifically, Dr. Garland finds that dietary vitamin D wards off postmenopausal breast cancer in women over fifty, but not in women who get cancer at younger ages.

In animals fed a high fat diet, which normally would produce a higher incidence of colon cancer, supplements of calcium and vitamin D blocked this carcinogenic effect of the diet. Vitamin D inhibits the growth of breast cancer in culture, and also seems to subdue human breast cancer. Cells from human prostate cancer were put into a "...permanent nonproliferative state", or shut down the cancer process, by the addition of vitamin D. Human cancer cells have been shown to have receptor sites, or stereo specific "parking spaces" for vitamin D.
