Breast Cancer Awareness Month: What Women Need to Know About Hormone Therapy in 2026

From the team at Revive Wellness

Every October, Breast Cancer Awareness Month gives us a chance to talk openly about breast health, early detection, and the questions women bring to us most often. At Revive Wellness, one question comes up more than any other: "Will hormone therapy increase my risk of breast cancer?"

It's an important question, and it deserves a thoughtful, evidence-based answer. Here's what the research tells us today, and how we approach this conversation with our patients.

Where the Concern Began

In 2002, early results from the Women's Health Initiative (WHI) study reported an increased risk of breast cancer among women using combined hormone therapy. The findings received widespread media attention, and hormone therapy use dropped sharply almost overnight. A boxed warning, the FDA's most prominent safety label, was added to estrogen products shortly after.

Over the following two decades, researchers took a closer look at the WHI data and found important context that was often missing from the original headlines:

The women in the study were, on average, in their 60s, many of them more than ten years past menopause. The combined therapy used a synthetic progestin rather than the micronized (bioidentical) progesterone commonly prescribed today. In the estrogen-only group, made up of women who had undergone a hysterectomy, breast cancer rates were actually lower than in the placebo group, a finding that held up in long-term follow-up. In the combined therapy group, the increase in absolute risk was small, estimated at less than one additional case per 1,000 women per year.

For perspective, other well-established risk factors such as regular alcohol use, weight gain after menopause, and physical inactivity carry comparable or greater risk.

What Changed in 2026

As the evidence evolved, so did the regulatory picture. In February 2026, the FDA approved labeling changes for six menopausal hormone therapy products, removing risk statements related to cardiovascular disease, breast cancer, and probable dementia from the boxed warning. The agency began this process in November 2025 following a comprehensive review of the scientific literature.

The FDA also noted that randomized studies show women who begin hormone therapy within 10 years of menopause onset, generally before age 60, experience reductions in all-cause mortality and fractures.

Despite these benefits, hormone therapy remains underused. In 2020, approximately 41 million US women were between the ages of 45 and 64, yet only about 2 million women in that age range received a hormone therapy prescription.

It's worth noting that some protections remain in place for good reason. The boxed warning for endometrial cancer was retained on systemic estrogen-only products, which is why women with a uterus who use systemic estrogen are prescribed progesterone alongside it. We also recognize that experts continue to discuss and debate these changes, and we stay closely engaged with the latest research as it develops.

Our Approach at Revive Wellness

Hormone therapy is not one-size-fits-all, and it isn't the right choice for every woman. Our providers take a personalized approach that considers:

Your age and time since menopause, your personal and family medical history, breast density and screening history, the type, dose, and delivery method of hormones, and your individual goals, whether that's better sleep, relief from hot flashes, bone protection, or simply feeling like yourself again.

For breast cancer survivors, care looks different and is always coordinated with your oncology team. Some survivors may be candidates for options such as low-dose vaginal estrogen, which has minimal systemic absorption and can significantly improve comfort and urinary health. Every case is evaluated individually.

Breast Health Reminders This October

Whether or not hormone therapy is part of your plan, a few simple habits go a long way in supporting breast health. Stay current on your mammograms. Review your mammogram report for breast density, since dense breast tissue can affect screening and may warrant additional imaging. Get familiar with how your breasts normally look and feel so you notice changes early. And know your family history, especially on both your mother's and father's sides.
