Any type of breast biopsy involves taking a tissue sample and sending it to a pathology lab for analysis. Most of us are familiar with the older surgical breast biopsy technique, which involves making an incision to draw out the entire lesion, which can leave a scar. Fine needle aspiration (FNA) uses a thin needle inserted into the breast to draw out cells. There is a chance that the smaller needle may miss a cancerous area and instead draw out regular cells, making a second biopsy necessary.
What Is a Core Needle Biopsy?
A core needle biopsy procedure is similar to a fine needle aspiration breast biopsy, however, the needle is larger. Since more breast tissue is removed through the hollow needle, the pathologist is better able to evaluate abnormal cells in the specimen, making a core needle breast biopsy more accurate than a fine needle aspiration biopsy. During this type of breast biopsy, the breast is numbed with a local anesthetic and the needle is used to draw out strands of tissue rather than just cells.
Breast Biopsy and Ultrasound
Ultrasound guidance is often used in core needle breast biopsies. A breast ultrasound can help the physician locate a lump in the breast, and determine if the needle successfully enters the area to obtain a significant sample. In most cases, this type of breast biopsy only takes a few minutes, and patients can resume normal activity afterward.
