RecruitingPhase 2Device studyEvaluation and Outcomes of SAVI Scout MD for Localized Breast SurgeryThe purpose of the study is to evaluate how precise the SAVI Scout MD is and how easy it is for surgeons to use during surgery. The SAVI Scout MD system uses tiny radar reflectors instead of wires, can be placed days or weeks before surgery, helps surgeons find the cancer more precisely and may lower the chance of needing a second surgery.
