A key advantage of this procedure is that the samples are larger than in FNAB and thus enhance the possibility of making an accurate laboratory analysis. • Guided CNB for Non-Palpable Growths: This procedure also uses a wide needle with a cutter that removes cores of tissue large enough to enhance the accuracy of laboratory analysis.
