Key Takeaways
Long-term HRT use is increasingly recognized as safe and beneficial
Dr. Green explained that official HRT guidance has evolved from older clinical recommendations to use the lowest dose for the shortest amount of time. Modern research points to benefits beyond symptom relief, including a lower risk of heart disease and osteoporosis when started early in the transition. Many women safely continue to use HRT long-term provided that it continues to help and the patient doesn’t develop any treatment contraindications.
Estrogen and progesterone play different roles in the body
Dr. Green explained that estrogen drives most of HRT's benefits, supporting heart, bone, skin, and vaginal health. Progesterone's main job is protecting the uterine lining from estrogen's stimulating effects. Women who have had a hysterectomy generally only need estrogen.
It's progesterone, not estrogen, linked to the small increase in breast cancer risk
Dr. Green cited research showing that progesterone, not estrogen, is associated with a small increase in breast cancer risk when the two treatments are combined. He noted how this clinical finding runs counter to what people might assume about HRT and cancer.
A family history of breast cancer doesn't rule out HRT on its own
Dr. Green explained that a family history of breast cancer alone does not make a person ineligible for HRT. High-risk scenarios, such as a known genetic marker like BRCA, change the benefit-risk ratio and usually means that care is better handled in person rather than through telehealth.
Initial side effects are common and usually temporary
Dr. Green noted that hormone levels take about three weeks to reach a steady state in the blood after starting or adjusting HRT. Hot flashes, bloating, and hair shedding are side effects that can appear early but typically resolve as the body adjusts. The benefits may take a few months to show up, but they last.
