After three decades of prescribing hormone replacement therapy and recently speaking at Harvard on this topic, I've witnessed countless women struggle with conflicting information about HRT. Should everyone be on hormones? Is it truly safe? What about the cancer risks we've all heard about?
In my recent conversation with my dear friend Natalie Jill, we dove deep into these questions that keep so many women awake at night (quite literally, due to hot flashes!). What emerged from our discussion is something I'm passionate about: the missing link in most HRT approaches is personalization and proper detoxification support.
The Dangerous "One-Size-Fits-All" Approach to HRT
Why Cookie-Cutter Hormone Therapy Fails Women
I see this all the time in my practice — and frankly, it breaks my heart. Women are either told "everyone should be on HRT" or "absolutely avoid it at all costs." The truth is far more nuanced.
Just last week, I had two women in their mid-50s come to my clinic with identical symptoms: mood swings, brain fog, hot flashes, and weight gain. Yet they left with completely different treatment plans. Why? Because as I always say, "menopause is natural and mandatory, but suffering is optional — and it takes more than hormones to fix our hormones."
The key factors I evaluate for each woman include:
Detoxification pathways — How well does her body process hormones?
Toxic exposure history — What environmental burden is she carrying?
Stress levels and nervous system health
Nutritional status and metabolic health
Genetic markers for hormone metabolism
Think of your health like a bicycle wheel. All the spokes — medical, psychological, environmental, relational, and lifestyle factors — must be strong for the wheel to roll smoothly.
The Cancer Question That Keeps Women Up at Night
Let me address the elephant in the room: "Dr. Anna, will hormones give me cancer?"
In my years of practice, I haven't seen bioidentical hormones cause cancer when prescribed properly with attention to detoxification support. However, there's always an underlying cause we must address.
When someone receives a cancer diagnosis, we need to ask: What contributed to this over the past 10-15 years before diagnosis? Was it:
Long-term birth control pills?
Environmental toxins like glyphosate or formaldehyde?
Chronic inflammation from poor blood sugar control?
Severe vitamin D deficiency?
Compromised detoxification pathways?
I'll never forget a 47-year-old patient who came to see me seven years after a breast cancer diagnosis. She'd worked in a pulp mill with formaldehyde exposure and lived on a heavily sprayed farm. Her vitamin D level was 17 (severely deficient), and no one had ever addressed the underlying causes of her cancer. We addressed her detox pathways, optimized her nutrition, and she's now thriving at 65 — with carefully monitored bioidentical hormone support.
The Science Behind Safe Hormone Therapy
Not All Hormones Are Created Equal
This is crucial to understand: The research shows synthetic progestins, not bioidentical progesterone, significantly increase cancer risk.
The landmark 2008 EPIC trial by Dr. Fournier compared different forms of progesterone and found:
Synthetic progestins (like Provera): 3x increased breast cancer risk
Bioidentical progesterone: No increased risk (1:1 ratio)
Even more encouraging, the recent 10-million-woman Medicare study found that bioidentical hormones did not increase morbidity and mortality when compared to synthetic versions.
Your Detox Pathways: The Missing Piece
Here's what most doctors aren't telling you: You must have open detoxification pathways before starting any hormone therapy.
I always evaluate:
Estrogen metabolites in urine (2-methoxy and 4/16-hydroxy pathways)
Genetic markers for methylation, sulfation, and glutathione production
Liver and gut health — because phase 3 detox happens through bowel movements
Daily elimination — if you're not having at least one bowel movement daily, we have work to do
As Natalie astutely observed in our conversation, before menopause, monthly menstruation helps eliminate used hormones. Post-menopause, without proper detox support, hormones can accumulate in fatty tissues.
My Personalized Protocol for Safe HRT
Optimal Hormone Levels That Actually Work
For post-menopausal women, I aim for:
Estradiol serum levels: 50-80 pg/mL
Total testosterone: 40-80 ng/dL (with free testosterone 4-6%)
Always treating the patient, not just the labs
These levels provide symptom relief and protective benefits without overwhelming your system or suppressing natural function.
Testing: Why Blood Isn't Enough
Most physicians only check blood levels, but that's like looking at a single snapshot of a movie. I recommend:
Blood testing shows circulating hormone levels
Urine testing (like the DUTCH test) reveals how your body processes these hormones
This combination tells the complete story of your hormone metabolism and helps me customize your protocol safely.
Delivery Methods That Make a Difference
Transdermal (patches/creams): My preferred method for most women
Avoids liver metabolism
Reduces cardiovascular risks
More stable levels
Oral hormones: I'm cautious with these due to increased stroke and inflammatory marker risks
Pellets: Can be effective but risky if you need to stop suddenly — I've seen dangerous withdrawal effects
Pro tip: If you're using patches and they stop working, check if your pharmacy switched to generic. Brand-name patches often have better absorption!
The Testosterone Revolution for Women
Why Testosterone Matters More Than You Think
Here's something that might surprise you: You have more testosterone than estrogen circulating in your body, even after menopause. Testosterone converts to estrogen through aromatization, which is why I often focus on testosterone optimization first.
For application, I recommend the vulvar/vaginal area — you get increased sensitivity and pleasure without unwanted hair growth elsewhere. As I told Natalie, "Put it on your clitoris, not your chin!"
The Progesterone Paradox
Many doctors still believe women without a uterus don't need progesterone. This is outdated thinking based on old pharmaceutical studies.
Progesterone is a neuroprotective hormone that:
Converts to allopregnanolone, increasing calming GABA
Supports mood, sleep, and bone health
Provides cardiovascular protection
Offers anti-inflammatory benefits
I recommend progesterone for all women, regardless of uterus status, though I prefer cycling it to prevent receptor downregulation.
Red Flags and When to Proceed with Caution
The High-Dose Danger Zone
I'm seeing concerning trends with ultra-high-dose protocols that attempt to restore "youthful" hormone levels. I never want to suppress your body's natural function — there's no long-term research on these supraphysiologic doses.
Warning signs of excessive hormones:
Testosterone levels above 300 ng/dL
Estradiol levels in the hundreds
Loss of effect after initial improvement (receptor downregulation)
Mood swings or depression when stopping

The Future of Personalized Hormone Health
What excites me most about the current state of hormone therapy is our growing understanding of personalized medicine. We're moving away from the fear-based "hormones cause cancer" mentality and the equally dangerous "everyone needs hormones" approach.
The truth lies in the middle ground — careful, individualized assessment with proper support systems in place.
Your nervous system, your genetics, your toxic burden, your stress levels — these all influence how hormones affect your body. When we address these factors holistically, hormone therapy becomes not just safe, but transformative.

Frequently Asked Questions
Q: Is it true that hormone replacement therapy increases cancer risk?
A: Synthetic progestins (like those in the original Women's Health Initiative study) do increase cancer risk. However, bioidentical hormones, when used with proper detoxification support and monitoring, have not shown the same increased risk. The key is addressing underlying factors and ensuring your body can properly metabolize the hormones.
Q: What's the difference between blood and urine hormone testing?
A: Blood testing shows your circulating hormone levels at a specific moment, while urine testing reveals how your body metabolizes and eliminates those hormones over time. Both are necessary for a complete picture of your hormone health and to ensure safe, effective therapy.
Q: Do I need progesterone if I don't have a uterus?
A: Yes! This is outdated medical thinking. Progesterone is a neuroprotective hormone that supports brain health, mood, sleep, bone health, and cardiovascular function — benefits that every woman deserves, regardless of uterus status.
Q: What are the optimal hormone levels for post-menopausal women?
A: For post-menopausal women, I generally aim for estradiol levels of 50-80 pg/mL and total testosterone of 40-80 ng/dL, with free testosterone at 4-6%. However, these should always be individualized based on symptoms, genetics, and overall health status.
Q: How do I know if my detoxification pathways are working properly?
A: Key indicators include daily bowel movements, urine hormone metabolite testing (like DUTCH test), and genetic testing for methylation and detox pathways. If you're constipated, have high toxic burden, or poor genetic detox markers, we need to address these before starting HRT.
