An ultrasound-guided biopsy involves the removal of cells from a suspicious area within the body using a thin needle and hollow tube called a syringe. During ultrasound-guided biopsy, the physician passes a needle through the syringe into the area or organ being examined and uses it to remove the tissue or fluid sample. Ultrasound is used by the physician to guide the needle to the appropriate area. The sample of tissue or fluid then is evaluated in the laboratory to determine your diagnosis.
Biopsies can be performed using surgery if the suspicious area is near the skin’s surface or can be removed during surgery. If the suspected tumor is
deeper in the body and cannot be seen or felt by the physician, he or she may decide to perform an ultrasound-guided biopsy.
The main advantage of an ultrasound-guided biopsy is that it does not require an incision, although there is a disadvantage in some cases when the needle may not be able to remove enough tissue for analysis.
