Axillary lymph node dissection for t1a breast carcinoma. Is it indicated?

Abstract

Axillary node positivity increases as the size of the invasive component increases and is an excellent predictor of DSF and breast cancer-specific survival. Consideration should be given to eliminating axillary node dissection for T1a lesions because of the low yield of positive nodes. Axillary node dissection should be performed routinely for T1b lesions and larger.
