Randomized Controlled Trial Multicenter StudyEffects of different hormone therapies on breast pain in recently postmenopausal women: findings from the Mayo Clinic KEEPS breast pain ancillary study.
Abstract Background: It is estimated that 70% of women in Western societies experience breast pain at least once during their lifetime. In the Women's Health Initiative (WHI), women treated with oral conjugated equine estrogen (0.625 mg) with or without continuous oral medroxyprogesterone acetate (2.5 mg) had a higher incidence of breast pain than those who received placebo. The effect of other hormone therapy regimens on breast pain is unknown. We compared breast pain among healthy, recently menopausal women enrolled in the Kronos Early Estrogen Prevention Study (KEEPS) at Mayo Clinic. ⋯ Four years of treatment with o-CEE at a lower dose than that studied in the WHI with cyclic m-P or transdermal E2 with cyclic m-P did not increase breast pain in healthy, recently menopausal women.
