I am just wondering: If you are postmenopausal, previously treated with tamoxifen, and then get a recurrence that is er positive, will it STAY er positive throughout the treatment? (Femara?) If you continue on the aromatose inhibitors after the main treatment, is it possible for the aromatose inhibitors to stop working, like tamoxifen does sometimes? I just wonder if the cells can mutate and change while you are being treated.
