Minimally invasive surgical alternatives are becoming more attractive for the treatment of malignancy due to improvements in technology, reduced costs and reduced morbidity. The main objective of this protocol is to determine the extent of ablation based on time and power parameters of the MedWaves in breast cancers. This would be accomplished in patients diagnosed with breast cancer who are already scheduled for breast cancer surgery. Prior to the surgical removal of the cancer, the microwave antenna would be inserted into the tumor under ultrasound guidance (either percutaneously or open). The tumor would be ablated, and then surgically resected in a standard, curative fashion.
