Is Hormone Replacement Therapy Right for You? Breaking the Myths and Embracing the Benefits
Hormone replacement therapy (HRT) is a topic surrounded by both curiosity and caution. As women approach menopause, questions abound: Is HRT safe? Does it really increase cancer risk? Should you consider it if you’re years past menopause? Let’s unravel the science, separate fact from fiction, and empower you with the knowledge you need to make informed decisions about your health and well-being.

Understanding the Importance of Hormonal Health After Menopause
For women entering perimenopause, menopause, and postmenopause, hormone changes are inevitable—and so are the symptoms. But it’s not just about hot flashes and mood swings. According to Dr. Betty Murray, clinical nutritionist, functional medicine practitioner, and CEO of Living Well Dallas, hormonal health plays a pivotal role in your whole-body health—particularly your bones, heart, brain, and even your skin.
Estrogen, progesterone, and testosterone are vital not only for reproductive health but also for maintaining bone density, supporting heart and brain function, and keeping your skin youthful. When these hormones decline, women face accelerated bone loss (and a greater risk for osteoporosis), cognitive changes, cardiovascular risk, and noticeable changes in skin structure.
Diet, lifestyle, and exercise matter, of course. But for many women, these factors alone might not be enough to counteract the impacts of hormone depletion. That’s why HRT is front and center in the conversation about healthy aging.
The Myth-Busting Origins: Where Did Fear of HRT Begin?
One of the most pervasive myths about hormone replacement therapy is that it increases the risk for reproductive cancers, particularly breast cancer, and cardiovascular disease. This fear can be traced back to a single, influential study: The Women’s Health Initiative (WHI).
Run in the 1990s, the WHI aimed to see if HRT reduced the risk of heart attack or stroke in women—many of whom were already years past menopause and had existing risk factors like obesity, high blood pressure, and smoking. The two main medications used were Premarin (an oral estrogen derived from horse urine containing 13 estrogens, only 3 of which are naturally made by humans) and medroxyprogesterone (a synthetic progestin associated with increased clot and inflammatory risk).
A subset of findings showed a minor statistical uptick: four in 1,000 women on Prempro (the combination HRT) developed breast cancer, compared to five in 1,000. The study’s own authors found this was not statistically significant—it could have been due to chance. However, this small increase was widely publicized, leading to a mass panic: doctors and patients alike abandoned HRT.
Crucially, what media and subsequent policy changes failed to report was that women who took estrogen alone actually had a reduced risk of breast cancer (in the same study, they saw a 23% reduction). Over the past two decades, thorough re-analyses and follow-up studies have confirmed that the initial fears were overblown—and, in fact, likely misleading.
The Truth About HRT: Updated Research and Reduced Risks
Fast-forward to today: the data is clear. Bioidentical hormone replacement therapy (BHRT)—where the estrogen, progesterone, and testosterone are molecularly identical to what the body naturally makes—does not increase the risk of reproductive cancers or cardiovascular disease when administered appropriately (ideally transdermal/topical for estrogen and testosterone, oral for progesterone).
The benefits? Multiple large-scale studies, including a newly released review in 2024 involving records of 10 million women over nearly two decades, found that HRT reduces the risk of death from all causes, including:
- Heart disease and stroke: No increased risk when topical/bioidentical forms are used—even in older women past their 60s or 70s.
- Dementia and Alzheimer’s: A stunning 23-34% reduction in risk, depending on the study.
- Breast, ovarian, and colorectal cancer: Reductions ranging from 11% to 32%.
The message is clear: when used correctly and tailored to the individual, HRT is not just safe but protective.
When Is the Best Time to Start HRT? Does Age Matter?
The “window of opportunity” for HRT is most open during perimenopause and the early menopausal transition, when the body is most receptive to the benefits of restoring physiologic hormone levels. But if you missed that window? All is not lost.
Research shows that even women in their 60s, 70s, and beyond can benefit—especially with bioidentical, topical formulations. HRT can protect your heart, bones, and brain, and support overall vitality. In Dr. Murray’s clinical experience, women started on HRT in their 60s and 70s continue to thrive well into their 80s.
Who Should Use Caution With HRT? Contraindications and Considerations
While HRT is safe and beneficial for the vast majority, some women need extra consideration:
- Strong family history of estrogen-sensitive cancers: This is a time for an in-depth, personalized consultation.
- BRCA gene carriers: The mutation itself doesn’t interact with estrogen; it increases cancer risk by impairing DNA repair. Decisions about HRT should be made individually with expert advice.
- History of stroke, deep vein thrombosis, or heart attack: Topical BHRT has shown to be protective rather than harmful, according to the latest data.
The key is working with a practitioner well-versed in menopause care—one who can assess your full health picture and monitor your response over time.
The Best Methods: How Should HRT Be Delivered?
Not all HRT is created equal. Dr. Murray recommends:
- Estrogen: Topical forms (patch, cream, or oil) to bypass the liver and minimize clot risk.
- Testosterone: Also topical for best absorption and safety.
- Progesterone: Oral forms are best, especially for sleep and relaxation benefits.
Pellets, injected into muscle or fat, are available but may not be as easily tailored to your changing needs.
HRT for Bone, Brain, and Beyond: The Takeaway
Restoring hormones to safe, low, physiological levels (about 10% of your premenopausal peak) does more than ease hot flashes—it protects your bones, keeps your arteries flexible, builds brain vasculature, helps your skin’s elasticity, and supports a healthy metabolism. In fact, HRT was FDA-approved for osteoporosis prevention in 1988, well before most bone drugs were available.
Bottom line: HRT, when guided by the latest science and an expert care team, is a cornerstone of healthy aging for women. Don’t let outdated myths rob you of vitality and protection.
