If a positive diagnosis occurs, the Breast Diagnostic Center facilitates care with the highly skilled members of the Cancer Center at Overlake ensuring that the patient receives seamless treatment.  

Breast Biopsy

When an abnormality is identified that is not clearly benign, tissue sampling is often recommended by the radiologist.  Most often this is done using image-guided needle biopsy, in which tiny samples (cores) of tissue are removed.  At Overlake Breast Health Center, subspecialty-trained, experienced radiologists perform all image-guided breast procedures. These include:

Ultrasound-guided core needle biopsy

Ultrasound is used to guide tissue sampling. The needle is visible "real-time" throughout the procedure.

Ultrasound-guided FNA (fine needle aspiration)

Ultrasound is used to guide placement of a needle into an area (usually a cyst).  Fluid and/or cells are removed using a syringe attached to the needle.

Stereotactic (mammography-guided) core needle biopsy

Mammograms are taken in pairs so that a computer can calculate the precise position of the needle. For this procedure, the patient is lying down with the breast in compression.

MRI-guided core needle biopsy

MRI scanning and intravenous contrast are used to image the area of concern, so that a computer can calculate the precise position of the needle. For this procedure, the patient is lying down with a plastic grid placed alongside the breast.
