Evidence supports the use of dual localizing tracer (blue dye and radio isotope) and harvesting
≥3 nodes or else do ALND to minimize false negative rate; any clipped positive nodes should be
localized for surgery.

In rare circumstances (e.g., a small T1aN1) it is possible to avoid radiation (see Justification of
Recommendation IIID).
