Hormone replacement therapies (HRT) are often prescribed to women facing menopause to help relieve harsh symptoms like hot flashes and dryness. The transition of menopause often begins for women around the ages 45 and 55 and is caused by a shift in the body’s sex hormone production. Estrogen and progesterone are two of the most commonly used hormones and there are currently around 12 million users of HRT. A study recently published in the journal The Lancet based on an analysis of data from 58 other studies on HRT, revealed that the longer a woman uses HRT, the greater the risk she has of developing breast cancer. It also concluded that in comparison to women who use estrogen-only hormone therapies, women who use estrogen-progestogen hormone therapies have greater risks for breast cancer. This research is important for both doctors and women to take into consideration before deciding to begin hormone replacement therapy and Dr. Janice Rymer, gynecologist and vice president of the Royal College of Obstetricians and Gynaecologists in the United Kingdom, stated, “The link between HRT and an increased risk of breast cancer has been known for some time. But it is a complex relationship.”
