OUTLINE: This is a randomized, placebo-controlled, double-blind study. Patients are stratified according to the phase of the menstrual cycle at time of biopsy and time of surgery (follicular phase [i.e., during first 7 days of menstrual cycle] vs luteal phase [i.e., after day 7 of the menstrual cycle]). Patients are randomized to one of two treatment arms.
