Does Bioidentical Hormone Therapy Cause Cancer?
Let’s talk about something that many of my clients are asking lately—bioidentical hormone therapy (also known as BHRT). You’ve probably seen it talked about online, or maybe even heard it offered at a spa or clinic. But is it safe? And more specifically, can it cause cancer? Let’s break it all down in simple terms.
🧬 What Is Bioidentical Hormone Therapy?
BHRT uses hormones that are molecularly identical to what your body makes naturally—like estrogen, progesterone, and sometimes testosterone. It’s commonly used to relieve symptoms of perimenopause and menopause, such as:
Hot flashes
Brain fog
Mood swings
Vaginal dryness
Sleep issues
Decreased libido
Weight gain
Erectile dysfunction
The goal is to bring your hormone levels back into balance and improve your quality of life.
🧪 What’s the Difference: Regulated vs. Compounded BHRT?
There are two main ways bioidentical hormones are provided:
1. FDA-Approved BHRT (Commercial Products)
These are standardized, tested for safety, and produced in monitored pharmaceutical facilities.
Commonly prescribed options include transdermal estrogen patches and oral micronized progesterone as well as injectable testosterone for men.
2. Compounded BHRT
Compounded BHRT is custom-prepared by a licensed compounding pharmacy based on a patient’s specific needs.
It can come in forms like lozenges, creams, capsules, or topical solutions not commercially available.
These pharmacies follow state and federal regulations, including oversight by boards of pharmacy and sometimes the FDA and U.S. Pharmacopeia (USP) standards.
At Lux Health, we work only with trusted 503A compounding pharmacies that meet rigorous quality and safety guidelines. These facilities are licensed and inspected to ensure that the medications they produce are consistent and safe for patient use.
💥 Does BHRT Cause Cancer?
👉 What the Research Says:
Estrogen-only BHRT (often prescribed after hysterectomy): Not shown to increase breast cancer risk in most studies.
Some studies show a very slight increase in breast cancer risk, especially with synthetic progestins. We do not prescribe synthetic hormones at Lux Health as they are NOT bioidentical.
Estrogen + progesterone (especially oral micronized progesterone): Some research suggests a very small increase in breast cancer risk, but this is similar to lifestyle-related risks like daily alcohol use or being overweight.
Transdermal estrogen and micronized progesterone are associated with lower risks compared to older hormone types.
No strong evidence links testosterone therapy to prostate cancer in healthy men.
Monitoring is important—especially PSA levels and prostate health.
The key takeaway? BHRT does not cause cancer outright, but like any medical treatment, it should be used under proper medical supervision with individualized planning.
✅ What You Can Do
Talk to your provider about your symptoms, medical history, and goals.
Choose personalized therapy based on lab work, symptom tracking, and shared decision-making.
Stick with pharmacies and providers who follow strict safety and dosing guidelines.
Get routine health screenings (Women- mammograms and pelvic exams; Men- prostate exams).
💡 FAQs About Bioidentical Hormone Therapy
Q: What makes hormones "bioidentical"?
They are structurally the same as hormones your body naturally produces. Most are derived from plant sources like yams.
Q: Is compounded BHRT safe?
Yes—when prepared by a licensed compounding pharmacy that follows USP and pharmacy board regulations. Always make sure your provider uses a trusted facility.
Q: Do I need BHRT forever?
Not necessarily. The length of treatment depends on your symptoms, goals, and health history. It should always be re-evaluated periodically.
Q: Is BHRT right for me if I had breast cancer?
Generally no, especially for hormone receptor-positive cancers. Always talk to your oncologist before starting any hormone therapy. It does not entirely exclude you and often you can receive other hormones which can be beneficial.
