Hormone therapy (HT) was formerly known as hormone replacement therapy (HRT). It gives prescribed hormones - estrogen and progesterone or its synthetic form (e.g., progestin). Estrogen given alone is estrogen therapy (ET). This was commonly called estrogen replacement therapy (ERT).
Hormones can be given in many forms: Oral pills; estrogen patches and vaginal creams; and the vaginal ring, Estring.
According to the Food and Drug Administration (FDA), each women should consult her doctor about the overall risks and benefits of hormone therapy. Each woman should also discuss non-estrogen treatments with her doctor, too.
For some women, hormone therapy may increase their risk for:
For a woman with a uterus, estrogen increases the risk for endometrial cancer (cancer of the uterine lining). Adding progestin lowers this risk.
Discuss the possible benefits, risks, and side effects with your doctor. The decision should be based on:
A major study concluded that the harmful effects of a specific combination of estrogen and progestin therapy are likely to exceed the chronic disease prevention benefits for most women. If you decide to use HT, use the lowest dose that helps and for the shortest time needed.
When you take HT, consult your doctor about its continued use. You should also have regular medical checkups, as advised. Checkups should include a blood pressure reading, pelvic and breast exams, and a mammogram.
