Summary
Brief summary (as posted)
The purpose of this study is to test the effect of primary progesterone on overall and disease free survival in women with operable breast cancer. The study addresses two issues related to breast cancer surgery: * Circulating progesterone at the time of surgery might counteract the detrimental effect of estrogen on survival of women with operable breast cancer. * Events at the time of surgery may have an impact on the natural history of breast cancer
