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.


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.
