Summary

This study looks at whether a special ultrasound can accurately tell if breast cancer has been completely cleared from the lymph nodes after chemotherapy. About 150 women with breast cancer that has spread to their lymph nodes will have a tiny marker placed in the affected node before starting chemo. After treatment, doctors will use different ultrasound techniques to track changes in that node. The goal is to create a model that can predict which patients have no cancer left in their lymph nodes, potentially allowing them to safely skip a more invasive surgery to remove those nodes.
