Hormone Therapy Myths Debunked (Part 1): Cancer Risk, Estrogen, and Testosterone Truths
Summary
- Testosterone Doesn’t Cause Prostate Cancer: Based on modern research, testosterone replacement does not increase prostate cancer risk. The "saturation model" reveals that higher testosterone levels don’t continue to stimulate prostate cells once receptors are full.
- Bioidentical Estrogen Is Not the Same as Synthetic Hormones: Fear of breast cancer from estrogen often stems from studies on synthetic progestins. In contrast, bioidentical estrogen—especially when paired with natural progesterone—may actually be protective.
- Hormones Work in a Web, Not Isolation: Estrogen, testosterone, thyroid, DHEA—all interact. Effective therapy means optimizing the whole system, not just one lab number. Symptoms often speak louder than bloodwork.
