For decades, women have used hormone therapy to ease symptoms of menopause, such as hot flashes and sweating. This is called menopausal hormone therapy, and you may see it abbreviated as HT or MHT. You may also hear it described as hormone replacement therapy (HRT), postmenopausal hormone therapy (PHT), or postmenopausal hormones (PMH). 

In the past, many doctors and their patients believed HT had other health benefits besides helping menopause symptoms. But several well-conducted studies have led doctors to conclude that the risks of HT may outweigh the benefits for most women. Still, each woman may have different concerns that should be discussed with her doctor.

Here we will discuss what is known about how HT can affect a woman’s risk of getting certain cancers. We will not go into the possible effects of HT on other diseases like osteoporosis (bone thinning), stroke, heart disease, blood clots, and dementia.
