A new study published in The Lancet Oncology highlights an important health warning for women considering hormone therapy to manage menopause symptoms. The research found that women under age 55 with a uterus who use estrogen plus progestin have an increased risk of breast cancer compared to those who use estrogen alone. Progestin is a synthetic version of the hormone progesterone, which is given along with estrogen to prevent certain cancers in women who still have a uterus.
Different Needs for Different Women
Hormone therapy isn’t one-size-fits-all. Women who have had a hysterectomy — a surgery to remove the uterus — do not need progestin and can safely take estrogen alone. This is because, without a uterus, the risk of developing endometrial cancer caused by estrogen alone is eliminated. The new findings show that for these women, estrogen-only therapy may actually reduce the risk of breast cancer.
The study helps clarify confusing information that has lingered since the early 2000s, when the Women’s Health Initiative linked hormone therapy to health risks. That older research focused on older women who often began treatment long after menopause. This latest study, however, looked at what happens when women start hormone therapy closer to when menopause actually begins — in their 40s or 50s.
Risks and Benefits of Hormone Therapy
Hormone replacement therapy (HRT) remains the most effective treatment for many uncomfortable menopause symptoms, including hot flashes and night sweats. It can also help prevent bone loss. However, like any medication, HRT comes with risks. According to the Mayo Clinic, some women face an increased chance of heart disease, stroke, blood clots, and certain cancers.
This new research shows that timing, type of therapy, and individual health history play a huge role in determining the real risks and benefits. Women with a family history of breast cancer or other health concerns should have an open discussion with their healthcare provider about which type of therapy is safest.
What Women Should Do Next
Anyone considering hormone therapy should work with their doctor to choose the best option for their body and health history. Staying informed and asking questions can help women find relief from menopause symptoms while lowering the risk of long-term problems.
