Interventional Radiology - Tumor Biopsy
Many cancers are now diagnosed by needle biopsy. During this procedure, an interventional radiologist uses imaging techniques (such as CT, x-ray, ultrasound, or MRI) to guide the insertion of a fine needle into a patient’s tumor. A small amount of tissue is removed and then examined by a pathologist to determine if cancer cells are present. Needle biopsies are less painful, less disfiguring, and result in a shorter recovery time than conventional surgical biopsy procedures.
