Additionally, associated risk from progesterone seemed to be modified by estradiol concentrations. The 1981 Johns Hopkins study found that infertile women with progesterone deficiency had a premenopausal breast cancer risk that was 540% greater than that of women whose infertility was not related to their hormone status. The ones with progesterone only, lowered the proliferation rate by 400%. What the authors concluded was what they have shown is that estrogen is truly a stimulant of breast cancer and progesterone is a protector of breast cancer.
