Summary
This study looked at over 1,500 women with early-stage HER2-positive or triple-negative breast cancer who had no signs of cancer in their lymph nodes on ultrasound. Researchers wanted to see how often cancer actually spread to the lymph nodes during surgery. The goal was to find out if some patients could safely skip a sentinel lymph node biopsy, a procedure that checks for cancer spread but can cause side effects.
