My wife had stage 1 breast cancer 5 years ago - mastectomy then Carboplatin/Taxotere/Herceptin, then finish a year on Herceptin, then reconstruction (silicone gummy bear implant) then Tamoxifen (1 yr) and Arimidex (3 yr). After she finished Arimidex, a tumor showed up inside the scar tissue between the pectoral muscle in front of the impalnt and the skin. Histology indicates it is from the original tumor. It was excised with wide margins on all sides - no contact with either the muscle or skin. Now she is getting radiation. No one will say so outright but it appears that this tumor was simply something left over from the original surgery that floated around and landed on the pectoral scar tissue then got trapped when the reconstruction was done. Now, we are getting a recommendation of chemotherapy again (xeloda & herceptin) with more AI to follow. PET and CT were both negative for additional masses before the second surgery. Why does anyone think chemo is necessary now?
