Synthetic vs. Bio-Identical Hormone Replacement

This study that shows a difference between synthetic (estrogen-progestin) and Bio-Identical (estrogen-progesterone) hormone replacement therapy.  This study demonstrated no risk of breast cancer from progesterone (bio-identical) use. Furthermore, this study also shows that progestins (synthetic) were associated with a significant increase in breast cancer. Breast Cancer Res. Treat. 2007; Vol.:125-134.
