A fine needle aspiration or small biopsy is a relatively simple procedure performed under ultrasound guidance. It is a method of removing a small amount of fluid or tissue by passing a needle through the skin. A local anaesthetic is usually given; this is a relatively non-invasive, less painful and quicker method when compared to other methods of tissue sampling such as surgical biopsy.
Fine needle aspiration or small biopsies are often performed when a lump is found, for example in the thyroid gland in the neck, or if an abnormality is detected close to the skin surface or on an imaging test such as X-ray or ultrasound.
The fluid or tissue taken during the procedure is sent to a pathology laboratory for analysis.
