Sentinel Lymph Node Biopsy

Sentinel lymph nodes in the armpit are the first lymph nodes to which cancer cells would travel if they were to leave the breast. A sentinel lymph node biopsy involves removal of 1-3 lymph nodes through a small incision in the armpit, to check if the cancer has spread and help guide overall treatment. It is used in people who have already been diagnosed with cancer.

A negative result suggests that the cancer has not yet spread to nearby lymph nodes or other organs.

A positive result indicates that the cancer is present in the sentinel lymph node and that it may have spread to other nearby lymph nodes. This information can help us to determine the stage of the cancer and develop an appropriate treatment plan.
