At the end of the course of thermo-chemotherapy or chemotherapy alone, and following all pre-surgery evaluations, the surgeon and subject will make decisions on the extent of surgery to be performed. These decisions will be made on the basis of surgical and institutional standards, and those of the National Comprehensive Cancer Network (NCCN) Breast Cancer Treatment Guidelines. Subjects will undergo mastectomy or breast-conserving surgery. It is understood that some subjects will select mastectomy for treatment even when the surgeon recommends breast conservation. The surgeon shall document the reasons why either mastectomy or breast conservation was selected.
