Selective Image Guided Resection of Axillary Lymph Nodes

The goal of this clinical research study is to learn if it is feasible to use find (using ultrasound) and surgically remove cancer that has spread to the lymph nodes, during routine lymph node surgery. In standard care, all affected lymph nodes are removed. In this study, however, the cancerous lymph nodes will be removed separately and then the rest of the lymph nodes under the arm will be removed after that.
