The goggles show a fluorescent dye (indocyanine green, ICG) that is given during the operation and collects in lymph nodes.\n\nIn breast cancer surgery, the surgeon removes lymph nodes from the armpit (axilla) to check whether the cancer has spread. Some nodes can be difficult to see and may remain after the surgeon believes the removal is complete. This study looks at whether the goggles can reveal such remaining nodes after the surgeon has declared the axillary surgery finished.\n\nThirty patients having breast cancer surgery with removal of the axillary lymph nodes will take part. After the surgeon states the planned removal is complete, the surgeon will briefly re-examine the area using the goggles and the ICG signal. If additional glowing tissue is seen, the surgeon will decide-using normal surgical judgment-whether it is safe and appropriate to remove it. Any tissue removed this way is examined under the microscope to determine whether it is a lymph node and whether it contains cancer.\n\nThe study measures how often this additional examination finds cancer-containing nodes that would otherwise have remained, where these nodes are located, whether the finding changes the cancer stage, and how much extra time the examination takes. The study also records any side effects. The results will help determine whether this approach should be studied in a larger trial.",[71,72,73,74],"Breast Cancer","Breast Neoplasms","Sentinel Lymph Node","Lymphatic Metastasis",[76,77,78,79,80,81,82,83],"indocyanine green","near-infrared fluorescence","fluorescence-guided surgery","augmented reality","axillary lymph node dissection","residual nodal disease","sentinel lymph node","breast cancer","NOT_YET_RECRUITING","2026-07-06",{"date":87,"type":88},"2026-07-10","ACTUAL",{"date":87,"type":65},{"date":91,"type":65},"2027-12-31",{"name":5,"class":6},1]
