51 years old-premenopausal (regular as clockwork!) Dx with IDC, stage I: Lymphs clear. Will start radiation soon. Post radiation, surgeon is recommending Arimidex. From my research,looks like Tamoxifen is right for me until menopause, and then would go on Arimidex. Any reason why he would choose to start me on Arimidex? Will be seeing him this week, would like to have some solid questions to ask.Also, do general surgeons ( mine is a breast specialist) usually mangage the hormonal therapy or should an oncologist be consulted even though no chemo is warranted?
