WHAT IS THE SENTINEL LYMPH NODE?
The sentinel lymph node is the first node(s) in the body to come into contact with the cancer cells as they leave the organ of origination and start to spin off or spread into the rest of the bodys tissues. In the context of breast cancer the usual location for the sentinel node (SN) is under the arm, although for cancers on the inner or medial aspect of the breast, the SN may be inaccessible in nodes beneath the breast bone or sternum.
