Sentinel Lymph Node Biopsy in Breast Cancer surgery
A surgical diagnostic procedure used to ascertain whether cancer has spread beyond a primary tumor into the lymphatic system, most commonly in evaluating breast cancer.
Sentinel Lymph Node Biopsy Treatment
The sentinel nodes are the first few lymph nodes into which a tumor drains. Sentinel node biopsy involves injecting a tracer material that helps the doctor in locating the sentinel nodes during surgery. The sentinel nodes are then removed and analyzed in a laboratory.
If the sentinel nodes are free of cancer, then cancer is unlikely to have spread, so removing additional lymph nodes is not advised.
If a sentinel lymph node biopsy reveals cancer, the surgeon might recommend removing more lymph nodes.
