What is Sentinel Lymph Node Biopsy?

Related Media: Mastectomy Lumpectomy

This biopsy is done to determine if cancer cells have spread from the tumor to nearby lymph nodes. Cancer often spreads from the tumor to the nearest lymph node or nodes. These lymph nodes are called the sentinal nodes. It is important to understand that the sentinel node will probably be the first one to get cancer if the cancer has spread. In the case of breast cancer, the sentinal nodes are often found in the armpit.
