Evaluating lymph nodes is an important step in identifying whether cancer cells have spread outside their site of origin. A "sentinel node" is the first lymph node where cancer cells are most likely to be detected away from the primary tumor.
A sentinel lymph node biopsy is performed to locate and remove the sentinel node(s). The day before surgery, a radiologist performs a radioisotope (dye) injection for lymphatic mapping. On the day of surgery, the surgeon also injects a dye (a different type) in order to optimize the chance of finding the sentinel lymph node(s). By using both modalities, this increases the accuracy of sentinel node identification. This sentinel lymph node biopsy facilitates the staging process and helps determine if any further treatments are needed.
