Ultrasound Guided Fine Needle Aspiration (FNA)
A Breast Fine Needle Aspiration (Ultrasound Guided Fine Needle Aspiration) (FNA) is a quick and simple procedure to remove fluid or cells from a breast lesion or cyst (a lump, sore or swelling) with a fine needle similar to a blood sample needle. The sample fluid or cells are sent to a pathology laboratory to be examined by a specialist doctor (a cytologist).
