Brief Summary:
The purpose of this study is to find out how often the researchers can avoid an ALND in patients with early-stage, node-positive HR+/HER2- breast cancer who are having upfront surgery. The study researchers think that, if AUS before surgery can help identify people who may have only 1 or 2 affected lymph nodes, it will be possible to perform the less radical standard SLNB during surgery.

Group/Cohort Intervention/treatment
Breast Cancer
Patients with cT1-2cN1 HR+/HER2- tumors who are scheduled to undergo upfront surgery will undergo AUS at the enrolling institution to characterize suspicious-appearing lymph nodes, as is part of routine practice.
Procedure: Breast surgery
Patients will undergo SLNB with dual-tracer mapping with technetium-99m sulfur colloid and lymphazurin blue dye, in accordance with routine clinical practice.

Primary Outcome Measures :
  1. evaluate rates of axillary lymph node dissection [ Time Frame: 2 years ]
    Completion ALND will be required if metastases are present in ≥3 SLNs on pathologic evaluation.
