Sentinel lymph node biopsy: A sentinel lymph node biopsy has two parts: first, the primary (sentinel) lymph node to which a tumor may be metastasizing is identified following intravenous injection of a radioisotope in the tissue surrounding the tumor (e.g. breast cancer). Second, the sentinel lymph node is removed and tested for cancer cells. A negative histochemical result argues against further removal of surrounding lymph nodes.

Sentinel lymph node biopsy: Removal and examination of the sentinel node(s) (the first lymph node(s) to which cancer cells are likely to spread from a primary tumor). To identify the sentinel lymph node(s), the surgeon injects a radioactive substance, blue dye, or both near the tumor. The surgeon then uses a scanner to find the sentinel lymph node(s) containing the radioactive substance or looks for the lymph node(s) stained with dye. The surgeon then removes the sentinel node(s) to check for the presence of cancer cells.
