Sandy, a Neoprobe (small handheld device) is used to measure the radioactivity from the liquid (blue dye) that was injected during your lymphatic mapping procedure. The high Neoprobe count identifies the sentinel nodes. Sentinel nodes are the first nodes that drain a cancerous area. If the sentinel nodes are non-cancerous, it is unlikely that the cancer has entered the lymphatic system.
