S/P Mast and still with positive margins

@karmicmom,

I don't know the answer to your main question. You also asked about tamoxifen, but to answer that, people will need to know whether your tumor is hormone-receptor positive. That information should be in the pathology report from your surgery, if you have gotten it yet, and may also be in the reports from your biopsies. You can add the information to "My Diagnosis" (click the My Profile link at the top right corner of the screen, then the "My Diagnosis" tab, click the "Add Diagnosis" button, and fill in the questionnaire. The information will then appear below your posts if you check the "Attach signature" button before submitting.) More information about your particular kind of breast cancer will help people give you a better answer to your questions.

Best wishes for successful treatment!

@karmicmom, it also depends on whether you are pre- or post-menopausal. I am sure your oncologist can advise you about when to start taking tamoxifen, if it's appropriate for your treatment.
