The Truth About HRT Safety — And the 2002 Study That Got It Wrong
In 2002, a study called the Women's Health Initiative (WHI) made headlines claiming HRT increased the risk of breast cancer and heart disease. Millions of women stopped their hormone therapy overnight. Doctors stopped prescribing it. A generation of women was undertreated.
Here's what that study actually showed: the hormones used were synthetic — not bioidentical — and included Premarin (conjugated equine estrogen) and medroxyprogesterone acetate, a synthetic progestin with a very different profile than natural progesterone. The participants were also older (average age 63) and many had pre-existing cardiovascular risk factors.
Subsequent analysis of the WHI data — and decades of research since — shows that bioidentical hormone therapy initiated at the right age (ideally within 10 years of menopause onset) is associated with reduced cardiovascular risk, preserved bone density, reduced dementia risk, and improved quality of life.
The fear was understandable. The science has caught up. We prescribe modern bioidentical therapy to appropriate candidates with careful monitoring — and we take the time to review the actual evidence with every patient.
