    For more than two decades, fear stemming from early, oversimplified interpretations of the Women’s Health Initiative led many women and clinicians to avoid hormone replacement therapy, culminating in a black box warning on estrogen. In 2025, the FDA removed that warning for estrogen-only therapies, reflecting clearer evidence that risks depend heavily on age, timing, hormone type, and route of administration—not the universal danger once assumed. Updated research shows that starting hormone therapy within ten years of menopause, using bioidentical formulations, and choosing non-oral routes can significantly reduce risks, while estrogen-only therapy has not been shown to raise breast cancer risk. The label change does not mean hormone therapy is risk-free, but it does open the door to individualized, evidence-based decision-making. With better data and more nuance, women and clinicians can move forward with informed conversations rather than fear-driven avoidance.
