Almost every week, a woman sits across from me with hot flashes, insomnia, and one big fear: "Will estrogen give me breast cancer?" It is the right question to ask. It deserves a better answer than a quick "yes" or a reflexive "no." Here is what I tell her. The best randomized evidence shows that estrogen taken alone did not raise breast cancer risk, and actually lowered it. Most of the risk seen in older studies was tied to the type of progestogen given with estrogen. And there are real exceptions and real uncertainties that we need to talk through together. My practice is built on shared decision making. My job is to give you accurate, balanced evidence in plain language. Your job is to weigh it against your symptoms, your values, and your own health history. Every treatment carries some risk, including doing nothing. You have the right to make an informed choice about your own body, and I will support that choice with the best information available.
