An interventional procedure (commonly known as a biopsy) involves obtaining tissue samples to determine whether abnormal cells are present. A biopsy is necessary when imaging studies cannot clearly define an anomaly, and can confirm benign (non-cancerous) or malignant (cancerous) tissue
During the procedure, a radiologist uses ultrasound to guide a needle into tissue to obtain samples
This biopsy extracts samples from an area of abnormal tissue.
A hollow needle withdraws tiny cores of tissue and is most often done using a local anesthetic.
A very fine needle is used to take fluid samples from cysts or lymph nodes.
Needle-localized biopsies use very thin needles or guide wires to mark the area that needs to be surgically sampled. These are typically done using ultrasound to precisely place the wire, but may also be done using mammography.
This procedure uses mammographic imaging to precisely identify and biopsy an abnormality within the breast.
