Although hormone supplements have been implicated in increased rates of breast cancer, they appear to mitigate the mortality risk of breast cancers that do develop. Compared with women who did not use hormone therapy, women who took estrogen-progestin were 63 percent less likely to die from breast cancer while those who took oestrogen alone were 30 percent less likely.
