Stacey, I agree with Maria - the oncologist might be recommending Arimidex because of the slight vidence of being progesterone-receptive. And she's post-menopausal, which qualifies her for Arimidex; it's not effective pre-menopause. so maybe he's considering it a good "just in case" backup drug. But if she's having lots of issues with it, I'd have her get the doc to tell her exactly the risk of recurrence with/without it, then go from there. As usual, it's a case of weighing the risk against the side effect of the drug. good luck- PJH
