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 contextsWhy “have” vs. “had” breast cancer changes the HRT conversationHow screening, overdiagnosis, and rising mastectomy rates intersectThe difference between natural progesterone and synthetic progestinsHow iodine, DIM, selenium, and vitamin D factor into prevention programsWhat estrogen metabolites (2-hydroxy vs 4-hydroxy) and COMT mean for riskWhere integrative oncology and repurposed therapies fit into patient-centered careEpisode Timeline Highlights00:00:51 LTED explained: estrogen reintroduction & apoptosis 00:06:48 How long is “long-term” deprivation?
