Definitions for "Sentinel Node Biopsy"
Removal of only one or a few lymph nodes to determine whether breast cancer is likely to spread elsewhere in the body. The sentinel node is the first lymph node to which a tumor drains (and therefore, the most appropriate lymph node to examine for evidence of cancer)
The lymphatic pathway from the breast cancer is tracked, using a radio-isotope label or blue lymphatic dye to allow biopsy of the first lymph node in that lymphatic pathway (sentinel node). This technique is still under evaluation
an experimental procedure in which only the sentinel nodes are removed and tested for the presence of cancer cells
a fairly new procedure and should be performed by a skilled and experienced surgeon
