Ultrasound-Guided Cyst Aspiration 

Ultrasound-guided cyst aspiration is a simple procedure performed by placing an ultrasound probe over the site of a breast cyst and numbing the area with local anesthesia. The breast radiologist then places a small needle directly into the cyst and withdraws fluid.

A technologist and radiologist work together during the cyst aspiration procedure. The patient lies on their back or are turned slightly to the side on a padded table. Warm gel is placed on the breast and ultrasound is used to identify the location of the cyst(s). The Radiologist inserts a thin needle into the breast to drain the cyst(s). The patient may feel a pinch and slight pressure at this time. The fluid from the cyst drains into a syringe and the cyst collapses. Depending on the appearance of the fluid, it may be discarded, or sent to the laboratory for analysis. A bandage is applied over the puncture site. There may be some slight bruising or swelling. The cyst aspiration procedure takes between 15-30 minutes to complete.
