Keeping Abreast, Dr. Jenn Simmons Welcomes Dr. Jeffrey Dach Podcast
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 How entrenched medical dogmas persist despite new evidence.

108: Estrogen Myths & Bioidentical Truths with Jeffrey Dach, MD (Part 2)
In the conclusion of this two-part conversation, Dr. Jenn Simmons and Dr. Jeffrey Dach go deeper on bioidentical hormones, long-term estrogen deprivation (LTED), and why “have” vs. “had” breast cancer matters when discussing HRT. They examine apoptosis after LTED, the role of estrogen in genomic stability, and how overdiagnosis from screening can drive unnecessary treatment. They also cover practical prevention pillars—iodine, DIM, selenium, and vitamin D—and what thoughtful, individualized care can look like for women navigating menopause and survivorship.
In This Episode, You Will Learn:
How reintroducing estrogen can trigger apoptosis in specific contexts.
Why “have” vs. “had” breast cancer changes the HRT conversation.
How screening, overdiagnosis, and rising mastectomy rates intersect.
The difference between natural progesterone and synthetic progestins.
How iodine, DIM, selenium, and vitamin D factor into prevention programs.
What estrogen metabolites (2-hydroxy vs 4-hydroxy) and COMT mean for risk.
Where integrative oncology and repurposed therapies fit into patient-centered care.

Dr. Jenn Simmons started her professional career as Philadelphia’s first fellowship trained breast surgeon and spent 17 years as Philadelphia’s top breast surgeon.

In 2019, Dr. Simmons founded Real Health MD, a virtual medical oncology practice supporting women at any stage of the breast cancer journey—from prevention and diagnosis to post-treatment recovery.
