Summary

This study aims to see if a less invasive biopsy method, using ultrasound guidance, can accurately detect whether breast cancer has spread to nearby lymph nodes. Researchers will enroll 200 adults with newly diagnosed breast cancer. The goal is to find the best way to identify suspicious lymph nodes and confirm cancer spread with a needle biopsy, potentially avoiding more invasive surgery.
