A Progestin is NOT Progesterone
Progestin is not the same as bioidentical progesterone. In fact, Progestins are "chemicalized " versions of progesterone. The chemical structure is altered to get a patent. That's why they are so bad for your health. They have been altered chemically.
Breast Cancer Rates Fall After Women Abandon Synthetic Hormones
Secondly, when the WHI results were made public, prescriptions for synthetic hormones dropped and breast cancer rates plummeted. Two separate studies showed these findings: Both in a Canadian Study and a US Study (April 2007 NEJM), data showed plummeting breast cancer rates after the 2002 WHI study prompted massive numbers of women to abandon synthetic hormones.
Bioidentical Hormones Are Not Associated with Breast Cancer
The French Cohort Study showed no increased risk of breast cancer in bioidentical hormone users compared to the general population. (3) The French Cohort Study was done in France. Questionnaires were filled out by eighty thousand women over 8 years of follow up. The authors found 2,354 cases of invasive breast cancer among 80,377 postmenopausal women. They found that, for the Bioidentical Hormone users (using estrogen plus progesterone), the risk of breast cancer was the identical to HRT-Never-Users (the same as the general population). However, for Synthetic Hormone users (estrogen plus progestin), the incidence of breast cancer was increased by 70 per cent. Sound familiar? The authors concluded that it was preferable to use progesterone rather than progestin, in order to avoid the increased risk of breast cancer associated with the Synthetic Progestins (such as Provera-medroxyprogesterone)
Conclusion: Synthetic Hormones are monsters to be avoided. Bioidentical hormones are natural to the human body and are far preferable. While synthetic Progestins cause breast cancer, natural progesterone is protective and prevents breast cancer, Why not use it?
