Sentinel Lymph Node Biopsies
Sentinel Lymph Node Biopsy for Breast Cancer
When breast cancer spreads, it usually spreads to the axillary lymph nodes. Within the lymph nodes, the sentinel nodes are where the cancer is most likely to spread. Sentinel node biopsy is a minimally invasive technique that allows analysis of the sentinel node. The sentinel node (the first lymph node draining a cancer) is identified during surgery after the injection of a radiolabeled tracer (technetium-99m labeled sulfer colloid) and colored dye (isosulfan blue) around the cancer. Sentinel node biopsy is often done as an outpatient procedure. It is very successful in identifying the sentinel node and allows precise evaluation of the axillary lymph gland.
