Thank you all for your responses and advice. <3
@arpie my radiation oncologist said radiation would cut my recurrence chances down by half, so to me that makes me feel that it's the right thing to do. I too have been told no chemo but most likely Tamoxifen but I will know more on Monday. I live in Balmain, Sydney.
@kmakm, that's right. Initially diagnosis was high grade DCIS (9cm tumor) but pathology results post-mastectomy showed minor invasion. Thanks for the suggestion of genomic testing. I have a family history so I am open to any additional testing beyond just BRCA.
