What is a needle localization?
A needle localization is requested when abnormal tissue is found and the lump or affected tissue is too small to feel. Needle localization is performed by a radiologist the same day as a surgical breast biopsy is scheduled. Using mammography and/or ultrasound, the radiologist guides a wire marker next to the suspicious area so that the lesion may be removed during surgery. This procedure increases the accuracy of the breast biopsy.
