New study links hormone therapy during perimenopause to reduced risks of breast cancer, heart attack, and stroke

A new study suggests starting hormone therapy during perimenopause may lower risks of breast cancer, heart attack, and stroke. The research analyzed health records of over 120 million women, comparing outcomes for those starting hormone therapy during perimenopause versus after menopause or never using it. Experts caution that the study has limitations, including potential bias and a relatively short follow-up period, emphasizing the need for more research before making broad recommendations.
