The biggest myth about hormones that I want to put to rest is that they cause breast cancer. It is simply not true. And the fear around it has kept women away from one of the most important tools available for long-term health.

Hormones are the language your body speaks. There are more than 2,000 estrogen receptors in the body alone. When those receptors are not receiving the signal they were built to receive, the tissues they govern start to break down. That is not a metaphor. It is physiology.

In more than thirty years of practice, I have been asked about hormones at every stage of a woman's life, from teenagers whose periods have not yet arrived, to women navigating perimenopause, to patients who have been post-menopausal for decades. The questions change. The clinical approach changes. The stakes at different stages are different.

In this article, I walk through what I look for, when I look for it, and why, including the five-year window after menopause that most women are never told about, and the difference between perimenopause, menopause, and post-menopause that almost everyone gets wrong.
