Sentinel Lymph Node Mapping
Sentinel lymph node mapping is a surgical technique used to identify the first one to three lymph nodes in the arm pit (axillary) area. The sentinel lymph node is thought to represent the “first” lymph node to receive drainage from the breast and is located by injecting a radioactive substance into the breast, just above the areola. The injection is performed at The Breast Center of Suburban Imaging.
In the hospital operating room, your surgeon will use a small probe to find the lymph node. This mapping assists in determining whether or not cancer is present in the axillary lymph node(s).
