Ultrasound-Guided Breast Biopsy

Ultrasound-guided core biopsy:

This technique obtains breast tissue without surgery. A biopsy needle is placed into the breast tissue. Ultrasound helps confirm correct needle placement - using sound waves reflected off breast tissue - so the exact location of the abnormality is biopsied. Ultrasound can distinguish many benign lesions, such as fluid-filled cysts, from solid lesions. Tissue samples are then taken through the needle.
