The Truth About Mammograms and Breast Cancer Screening: What the Data Really Shows with Dr. Jenn Simmons

The Truth About Mammograms and Breast Cancer Screening: What the Data Really Shows with Dr. Jenn Simmons

Author: Dr. Taz MD February 17, 2026 Duration: 1:08:23

Breast cancer screening is often treated as a given. Mammograms are framed as routine, early detection as unquestionably life-saving, and following guidelines as the responsible choice. But what if the full picture is more complicated?


In this episode of hol+, Dr. Taz sits down with integrative oncologist and breast surgeon Dr. Jenn Simmons, author of The Smart Woman's Guide to Breast Cancer, to explore what breast cancer screening data actually shows, where common narratives may oversimplify reality, and how statistics can sometimes be misunderstood by both patients and providers.


Together, they discuss the difference between screening and diagnostic imaging, why detecting more cancers does not always mean fewer deaths, and how concepts like overdiagnosis and lead-time bias shape our interpretation of outcomes. Dr. Jenn also explains how breast cancer behaves differently from many other cancers, why progression is not always linear, and what tumor markers like ER, PR, HER2, and triple-negative really indicate.

The conversation expands beyond imaging into a whole-body view of breast health, touching on inflammation, immune function, metabolic health, toxic burden, stress, and lifestyle as factors that shape cancer risk and recovery. Rather than promoting fear or urgency, this episode focuses on helping listeners understand their bodies, ask better questions, and make informed decisions with clarity.

This episode is for anyone who wants a deeper understanding of breast cancer screening, feels overwhelmed by conflicting guidance, or wants to approach breast health with more nuance and less panic.

About Dr. Jenn Simmons

Dr. Jenn Simmons is an integrative oncologist, breast surgeon, and founder of Real Health MD. She was Philadelphia’s first fellowship-trained breast surgeon and spent nearly two decades leading one of the region’s top breast programs before transitioning into integrative oncology.

Drawing from her experience in conventional cancer care and her own health journey, Dr. Simmons now focuses on whole-body approaches to breast health, cancer prevention, and recovery, including metabolic health, inflammation, immune function, lifestyle medicine, and root-cause healing. She is the author of The Smart Woman's Guide to Breast Cancer, a patient-centered resource designed to help women better understand their diagnosis, ask informed questions, and navigate treatment decisions with clarity rather than fear.
