A Core Needle Biopsy is a medical procedure used to obtain a small sample of tissue from a suspicious area, often in the breast or other organs. This technique involves using a hollow needle to extract a cylindrical piece of tissue, which is then examined under a microscope for signs of disease, such as cancer. It is less invasive than surgical biopsies and typically requires only local anesthesia. The procedure is usually guided by imaging techniques like ultrasound or CT scans to ensure accurate placement of the needle. Core needle biopsies are generally quick, with minimal recovery time, allowing patients to return to their normal activities shortly after the procedure.
