Brief Summary

This single-center, randomized study aims to compare the intraoperative detection rates of axillary lymph nodes marked with carbon suspension versus metallic markers in breast cancer patients (T1-3N1M0) before neoadjuvant therapy. Primary endpoint: frequency of marked lymph node identification during surgery. Secondary endpoints: time from marking to surgery and quality of life (EORTC QLQ-BR23).
