Trial aims to spare breast cancer patients from risky, unnecessary surgery

This study is for people with breast cancer that has spread to lymph nodes in the armpit, which is visible on an ultrasound before surgery. It will test if a less extensive surgery, which removes only the first few key lymph nodes, is just as effective for survival as the standard, more invasive surgery that removes many more nodes. The goal is to see if this less invasive approach can reduce the risk of long-term arm swelling and mobility problems without compromising cancer outcomes.
