A needle biopsy is a medical procedure used to collect a small sample of tissue from a specific area in the body. This is often done to diagnose conditions like cancer or infections. During the procedure, a thin needle is inserted into the area of concern, guided by imaging techniques such as ultrasound or CT scans. The doctor then extracts a tiny piece of tissue for examination under a microscope. The procedure is usually quick and can be performed in a doctor's office or clinic. Patients may experience some discomfort, but it is generally less invasive than traditional surgery. Results from a needle biopsy help doctors determine the best treatment options for conditions like tumors or inflammatory diseases.
