Needle Biopsy of the Breast

While ultrasound and MRI are excellent ways to evaluate breast abnormalities found during a mammogram, sometimes it is still not possible to tell whether a growth is benign (non-cancerous) or malignant (cancerous). In an ultrasound-guided needle biopsy, the radiologist uses the real-time ultrasound images to locate the precise location of the mass and guide a biopsy needle into the mass to withdraw some tissue. This tissue is then sent to the pathology department to determine if it is cancerous.

Needle Breast Biopsy exams are available at the following Advanced Radiology locations

A breast ultrasound uses high-frequency sound waves to generate images of breast tissue. First, the radiologist or radiology technologist places gel on the skin and moves the ultrasound transducer, or wand, over the area of concern. The radiologist will cleanse the areas and give you a local “numbing” anesthetic. You will be awake during the biopsy and should have little or no discomfort. A thin needle is used to withdraw tissue samples to send to pathology. A dressing will be placed over the biopsy site and should remain in place for 24 hours.

No prep. Patients are encouraged to eat a small breakfast before they come in.
