Sentinel Node Localization Helps Determine If Cancer Has Spread To Lymph Nodes

Sentinel node localization is a nuclear medicine study used to determine if cancer has spread to the lymph nodes.

A contrast agent (often called a dye) is used that “settles” in the lymph nodes if cancer is present and can be viewed by the radiologist and surgeon to determine which (if any) lymph nodes should be removed.

Henry County Hospital surgeons use sentinel node localization for breast cancer and malignant melanoma.
