Supraclavicular Lymph Nodes Supraclavicular lymph nodes are a group of lymph nodes located in the hollow above the clavicle (collarbone) at the base of the neck. They are part of the lymphatic system, which plays a crucial role in the immune system by filtering lymph fluid and trapping foreign particles. These nodes are a significant area for potential metastasis from various cancers. | Dr. Najeeb
