The short answer:<\/strong> For most healthy women under 60 or within 10 years of their last period, hormone therapy is the most effective treatment for hot flashes, night sweats, and other menopause symptoms, and its benefits generally outweigh its risks. The headline scares from the early 2000s were based on a study group that was, on average, much older than the women who actually start treatment today. Timing, dose, and the type of hormone all matter, and the decision is individual, made with a clinician who knows your history.<\/p>\n

Hormone replacement therapy, now more often called menopausal hormone therapy (MHT), has had one of the most turbulent reputations in modern medicine. For two decades many women avoided it, and many doctors hesitated to prescribe it, based on an interpretation of one large trial that later research has substantially revised. Here is what the current evidence actually says.<\/p>\n

What HRT is, and what it does<\/h2>\n

Menopausal hormone therapy replaces the estrogen (and usually progesterone) that the ovaries stop producing around menopause. Estrogen is the active ingredient that relieves symptoms. Progesterone, or a synthetic progestogen, is added for any woman who still has her uterus, because estrogen on its own can overstimulate the uterine lining and raise the risk of endometrial cancer. Women who have had a hysterectomy can usually take estrogen alone.<\/p>\n

The strongest, most consistent benefit is relief of vasomotor symptoms, the medical term for hot flashes and night sweats. MHT is the most effective treatment available for these. It is also first-line for the genitourinary syndrome of menopause (vaginal dryness, discomfort, recurrent urinary symptoms), where low-dose vaginal estrogen works locally with very little absorption into the rest of the body. It prevents early postmenopausal bone loss and reduces fractures, and many women report better sleep, mood, and quality of life.<\/p>\n

The WHI study, and why it was misread<\/h2>\n

In 2002 the Women’s Health Initiative (WHI), a large randomized trial, stopped its estrogen-plus-progestin arm early after finding an increase in breast cancer risk. The news coverage was alarming, and prescriptions dropped sharply worldwide.<\/p>\n

Two things were lost in that coverage. First, the absolute risk was small. The trial reported roughly eight additional breast cancer cases per 10,000 women per year in the combined-therapy group, a real but modest increase. Second, and more important, the average woman in the WHI was in her early-to-mid sixties, well past menopause, and the trial used a specific oral combination: conjugated equine estrogens plus medroxyprogesterone acetate. The results were generalized to all women, all ages, and all formulations, which the data did not support.<\/p>\n

Later re-analyses of the WHI itself, along with subsequent research, painted a more nuanced picture. The estrogen-alone arm (for women who had had a hysterectomy) actually showed a neutral to slightly lower breast cancer risk. In 2025, US health authorities moved to revise the longstanding boxed warnings on hormone therapy products, reflecting this updated understanding. This is a genuine course correction, not a marketing claim.<\/p>\n

The timing hypothesis<\/h2>\n

The most useful idea to come out of the reinterpretation is the timing hypothesis<\/em>. It holds that when you start hormone therapy matters as much as whether you take it at all.<\/p>\n

Women who begin MHT close to menopause, generally under age 60 or within 10 years of their last period, tend to have a favorable balance of benefits and risks, including potential benefits for heart and bone health. Women who begin a decade or more after menopause, or after age 60, face a less favorable balance because the underlying risks of heart disease, stroke, blood clots, and dementia are higher to begin with. This is the framework endorsed by the 2022 position statement of The Menopause Society (formerly the North American Menopause Society).<\/p>\n

An important caveat: hormone therapy is not prescribed to prevent heart disease. Cardiovascular prevention is not an approved indication. The point is that starting earlier does not carry the cardiovascular penalty that the original WHI headlines implied.<\/p>\n

Risks, in proportion<\/h2>\n

Real risks exist, and they vary by formulation and how the hormone is delivered.<\/p>\n
