New ultrasound technique could spare breast cancer patients unnecessary surgery

This study looks at a special ultrasound technique to check lymph nodes during surgery in breast cancer patients who have already had chemotherapy. The goal is to see if this method can accurately tell whether cancer remains in the lymph nodes, helping doctors decide exactly which nodes to remove. About 97 women with breast cancer that spread to lymph nodes will take part, and the results could lead to less extensive surgery and fewer side effects.
