Estrogen Therapy: Benefits, Risks, and Who Should Consider It
Estrogen therapy relieves the most disruptive symptoms of menopause and protects bones. Modern practice makes the risk conversation much clearer than it was in the WHI era.
Documented benefits
Estrogen is the most effective treatment for vasomotor symptoms, reducing hot flash frequency by 75% within weeks. It restores vaginal tissue integrity, reduces urinary urgency and recurrent urinary tract infections, protects bone mass, and often improves sleep, mood, and cognition when started near the onset of menopause.
Real risks, in context
Oral estrogen slightly increases thromboembolism and stroke risk; transdermal estrogen does not, per multiple 2022+ meta-analyses. Combined therapy with older synthetic progestins added a small breast cancer risk after 5+ years; the risk with micronized progesterone appears substantially smaller. Absolute risks in a healthy 50-year-old remain low and are contextualized against lifestyle risks like alcohol and inactivity.
The timing hypothesis matters: benefits are greatest and risks lowest when therapy is started before age 60 or within 10 years of menopause onset. Late initiation in older women changes the risk profile.
How estrogen is delivered
Transdermal patch (twice weekly) or gel (daily) are first-line in most patients. Vaginal estrogen (cream, tablet, or ring) treats local genitourinary symptoms alone and is safe even in some breast cancer survivors after specialist review. Oral estrogen remains an option when transdermal is not tolerated or absorbed.
