107: Estrogen Myths & Bioidentical Truths with Jeffrey Dach, MD (Part 1)
In this thought-provoking episode of Keeping Abreast, Dr. Jenn Simmons welcomes Dr. Jeffrey Dach for a powerful discussion on bioidentical hormones, estrogen, and the myths that have shaped women’s health for decades.
Dr. Dach draws from over 40 years of clinical experience and research to challenge the mainstream narrative that estrogen causes breast cancer. Together, he and Dr. Jenn explore how estrogen protects DNA integrity, why natural progesterone is vastly different from synthetic progestins, and how iodine and testosterone play overlooked but vital roles in breast cancer prevention.
Along the way, they trace the history of hormone therapies—from DES and Tamoxifen to modern-day aromatase inhibitors—revealing both the progress and the persistent dogmas of conventional medicine. This is a conversation about evidence, empowerment, and the urgent need to rethink how we approach women’s health.
Because of its depth and importance, this conversation has been divided into two parts. This episode is Part 1 of 2.
In This Episode, You Will Learn:
- Why estrogen may protect against breast cancer rather than cause it
- The truth about estrogen receptors and how they shape cancer risk
- The critical difference between natural progesterone and synthetic progestins
- How testosterone supports breast cancer prevention
- Why iodine deficiency remains a hidden driver of disease
- The historical evolution of hormone therapies—from DES to Tamoxifen
