Breast Cancer, HRT
Women with a prior hysterectomy given estrogen-only HRT (conjugated equine estrogen) had a 23% reduction in breast cancer diagnosis compared to those assigned placebo. The 10,000 women were followed for more than 16 years. This was reported at the San Antonio Breast Cancer Symposium (SABCS) based on the Women’s Health Initiative (WHI), a long-term study of thousands of women covering many health measurements. That same group of women had 44% fewer breast cancer deaths compared to the placebo group.
