Description

Core needle biopsy is a minimally invasive diagnostic procedure used to obtain tissue samples from suspicious areas in the body for further examination. Here are some key points about core needle biopsy: 1. Procedure: During a core needle biopsy, a radiologist, pathologist, or surgeon uses a hollow needle to extract a small cylindrical sample, or core, of tissue from the suspicious area. The procedure is usually performed under local anesthesia, and imaging guidance, such as ultrasound, mammography, or computed tomography (CT), may be used to precisely target the area of interest. 2. Sample collection: The needle is inserted into the target area through a small incision or directly through the skin. The physician carefully advances the needle to the suspicious tissue and then applies suction or manually moves the needle back and forth to collect the tissue sample. 3. Pathological examination: The collected tissue samples are sent to a pathology laboratory, where they are analyzed by a pathologist. 4. Advantages: Core needle biopsy offers several advantages over more invasive procedures, such as surgical biopsy. It is a relatively quick and safe procedure that can be performed on an outpatient basis. 5. Limitations: Although core needle biopsy is highly accurate in many cases, there is a small risk of sampling error or false-negative results, meaning that the biopsy may miss the presence of cancer or other abnormalities. 6. Risks and complications: Core needle biopsy is generally a safe procedure. However, there is a small risk of bleeding, infection, bruising, or damage to surrounding structures. These risks are relatively low and are usually outweighed by the benefits of obtaining a tissue sample for accurate diagnosis and treatment planning. Core needle biopsy is an important diagnostic tool in modern medicine, allowing for accurate evaluation of suspicious lesions with minimal invasiveness.
