Sentinel Node Biopsy
A sentinel node biopsy is a procedure in which the sentinel lymph node is identified, removed, and examined to determine whether cancer cells are present.
A negative biopsy result suggests that cancer has not developed the ability to spread to nearby lymph nodes or other organs. A positive biopsy result indicates that cancer is present in the sentinel lymph node and may be present in other nearby lymph nodes (called regional lymph nodes) and, possibly, other organs. This information can help a doctor determine the stage of the cancer (extent of the disease within the body) and develop an appropriate treatment plan.
