In brief: Biopsy of lymph node
Lymph nodes are biopsied to see if cancer has spread beyond the primary site.
Using a radioactive tracer and dye, the lymph nodes closest to a tumor can be identified and biopsied without having to remove all the potential draining nodes which can lead to complications. Most often done with breast cancer and melanoma.
