Breast Needle Localization

A breast needle localization is an exam done to locate the abnormal area in question. The first part of the test can be done under ultrasound, mammography, or a combination of both.
The Radiologist (x-ray doctor) will look at your films and determine which modality will be used for your test. You will be sent to surgery following the needle localization.

Breast Needle Localization Procedure

The Radiologist (x-ray doctor) will insert a needle in the breast, into the area in question. Ultrasound/Mammography images will be taken to confirm needle placement. The needle will be exchanged for a wire, which will be taped to the skin. The wire will locate the area for the surgeon during surgery.
Procedure time: 1- 1½ hours.
