Fine needle aspiration


In FNA, a fine needle is inserted into the area of concern or, if there is a lump, directly into the lump. The needle is guided into the area or lump, usually using the ultrasound as the guide, allowing the clinician to clearly see the needle and the area of concern. The needle is used to take samples of any fluid that may be present. A FNA is commonly used to aspirate (drain) a cyst, which is a lump filled with fluid and is usually benign.

 The samples taken with the needle will be sent to the laboratory for analysis. A report is sent back to your doctor or specialist. FNA is performed  in the doctor’s or radiology rooms.
