Will your surgery be a lumpectomy or a single mastectomy or double? I opted for the single mastectomy as my breast like yours was starting to have what they thought was a fatty lump starting on the other side of the nipple. They all thought the sentinel node was fine and didn't even do a biopsy on it and then the testing after he took out the node it returned a positive for cancer result in pathology so it was back again for a full axillary clearance of all my underarm nodes but fortunately the pathology results showed them to be clear so at least we'd gotten to the bottom of it all. I just wish they had told me there was the possibility of having to have a second surgery after the first. I wasn't prepared for it at all and got every upset about it all at the time.
