Has anyone else been diagnosed at biopsy with PLCIS and been upgraded after surgery? I am waiting for a bilateral mastectomy next week and they will also remove the sentinel nodes. The doctor clearly said that this was a breast cancer yet all the literature suggest otherwise. He alos said that they cannot say if it is invasive or not until after pathology, but that he was hopeful that it was not. My research indoicates a high level of upgrade followimg surgery. Anyone have any further info?
