SCOUT Reflector for Tagging Lymph Nodes for Targeted Removal in Patients With Breast Cancer

This pilot clinical trial will evaluate whether the SCOUT reflector can be used to tag abnormal lymph nodes in patients with breast cancer prior to chemotherapy for targeted removal at the time of surgery. The SCOUT localization system with the SAVI reflector is non-radioactive and completely internal so can be placed into an abnormal lymph node prior to chemotherapy treatment, which theoretically will allow easier identification and therefore more reliable targeting of the abnormal lymph node for surgical removal.
