If yes, the important factors to consider are the type of cancer, the number of lymph nodes removed versus the number with cancer cells, and whether the cancer has spread beyond the lymph node. These factors help determine the stage of the disease, and possible treatments and outlook.

To see if cancer is present in the lymph nodes of the groin: A surgical procedure called a sentinel lymph node biopsy (SLNB) removes the first lymph node in a chain or group of lymph nodes that a particular cancer is most likely to spread to. Because the lymphatic system drains in a predictable pattern, the fluid from a particular area of the body will flow to specific lymph nodes. It is presumed that if the “sentinel” lymph node is free of disease, then other nodes around it will also be cancer-free. This is confirmed when the removed node is examined and tested in a laboratory. Test results help the doctor determine if cancer is present. If it is present, laboratory results help determine the stage of cancer, a treatment plan, and the long-term outlook of the disease.

How does cancer spread through lymph nodes?

Cancer cells are able to migrate through the lymphatic system and end up in a lymph node that is draining the primary site. For carcinomas that disseminate through the lymphatic system , they commonly spread to the regional node before spreading to the next tier of nodes. These immediate regional nodes are called the sentinel lymph nodes. If the clinician suspects an individual of having cancer, a biopsy or dissection of the sentinel lymph node that is draining the site of interest can help to determine if cancer has metastasized. Upon finding a cancerous cell in the sentinel lymph node, this information can assist with staging cancer and direct mode of therapy. [11][12][13]
