Bioidentical Progesterone Protects Against Breast Cancer – Part 1

*Bioidentical Progesterone is Protective Against Breast Cancer

Synthetic Progestin is NOT

The following article is presented for your consideration in response to a recent NEWS release that warned women of increased breast cancer risk when taking a synthetic combination of estrogen and progestin (Prempro). Unfortunately, the NEWS did not explain the decreased risk offered by natural (bioidentical) progesterone or explain the difference between biodentical hormones and  synthetic hormones.

The NEWS Release – October, 2010 / What the News Reported

“There is more evidence linking hormone replacement therapy with breast cancer in postmenopausal women. Women take HRT to ease the symptoms of menopause and keep them looking and feeling younger, but are the risks outweighing the benefits?

The study’s authors found that those who had used the therapy Prempro]  … were not only more likely to develop but to die from breast cancer.”

The NEWS reported a study that was a follow up to the Women’s Health Initiative Study in 2002]. That follow up study found that “not only are women taking HRT at increased risk of breast cancer, but their tumors are more likely to be more advanced, more deadly.”

The researchers in the Women’s Health Initiative Study looked at more than 16,000 postmenopausal women who were part of a large government study called the Women’s Health Initiative. The women took either Prempro, a drug made by Pfizer that combines both estrogen and progestin, or a placebo or sugar pill. In 2002 the study was stopped early after five and a half years of treatment because of concerns about heart health, breast cancer and other health problems.

The recent research looked at 11 years of follow-up on the health of the women who took the Prempro and the authors found that those who had used the therapy were not only more likely to develop but to die from breast cancer.
