The procedure includes the following steps: Lymphoscintigraphy takes pictures of the lymphatic system and is used to locate the sentinel lymph node. The procedure usually includes a special type of imaging test called lymphoscintigraphy. What happens during a sentinel lymph node biopsy?Ī sentinel lymph node biopsy may be done in a hospital or an outpatient surgical center. Other names: lymph node biopsy, sentinel node biopsy, sentinel lymph node mapping and biopsy Sometimes there is more than one sentinel lymph node.Ī sentinel lymph node biopsy can show how likely it is that your cancer is spreading (metastasizing). The node is usually located near the site of the original tumor. The sentinel lymph node is the first node where these types of cancers are most likely to spread. Cancers spread when cells break off from the original tumor and are carried to other parts of the body. Lymph nodes are located throughout the body, including the underarms, neck, chest, abdomen, and groin.Ĭertain cancers, such as breast cancer and melanoma (the most dangerous form of skin cancer), can spread through the lymphatic system. Lymph nodes are part of the lymphatic system, a network of organs and vessels that help the body fight infections and other diseases. 2018 36(4):399–413.A sentinel lymph node biopsy is a test that checks lymph nodes for cancer cells.
