Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — progesterone and breast cancer

Breast cancer is not one disease — it encompasses many distinct types with different attributes, degrees of invasiveness and treatment responses. Understanding the difference between invasive and non-invasive cancers, what hormone receptor status means, and which risk factors are modifiable can help women make more informed decisions about screening, lifestyle and hormone health. This article provides a clear, evidence-based overview.

The latest research confirms what Dr. John Lee and Dr. David Zava argued decades ago: maintaining healthy progesterone levels in proper balance with oestrogen is one of the most powerful tools women have for preventing and recovering from breast cancer. This article outlines seven practical steps to restore hormone balance and reduce breast cancer risk.

A landmark study published in Nature confirmed what Dr. John Lee and Dr. David Zava argued over a decade ago: natural progesterone — unlike synthetic progestins — can slow or even shrink ER+/PR+ breast cancer tumours. This article explains the receptor science behind the findings and what it means for women’s hormone health.
