Ultrasound may spare breast cancer patients unnecessary surgery

This study looks at whether a special ultrasound can accurately detect if breast cancer has completely disappeared from lymph nodes after chemotherapy. About 150 women with cancer that spread to their lymph nodes will have a small clip placed in a cancerous node before treatment. Doctors will then use different ultrasound techniques to track changes in that node. If the ultrasound can reliably show the cancer is gone, some women may be able to safely skip a more invasive surgery to remove lymph nodes.
