How do they do a needle biopsy?

A needle biopsy is performed by inserting a thin, hollow needle through the skin to obtain a sample of tissue from a specific area, such as a tumor or suspicious lesion. The procedure may be guided by imaging techniques like ultrasound, CT, or MRI to ensure accurate placement. After local anesthesia is administered, the needle is inserted and the sample is extracted, which is then sent to a laboratory for analysis. The procedure is typically quick, minimally invasive, and can be done on an outpatient basis.
