Yes. Breast cancer and endometrial cancer occur in tissue sensitive to gonadal hormones. Unopposed estrogen is the only known cause of endometrial cancer, though there may be other factors involved. Estrogen, or at least one or more of the various estrogens, are thought to contribute to breast cancer. Progesterone balances the estrogen level in the body, thus lessening the risk.
