Biopsy
A medical procedure used to diagnose a condition.
Most biopsies involve taking a small piece of skin or muscle under a local anesthetic. When the cells to be analyzed are accessible by needle, the biopsy specimen may be removed with a hollow aspiration needle, which is used to suck out the sample of cells. Aspirations are typically performed with local anesthesia; in addition, ultrasound imagery or other scanning devices may aid in locating the cells of interest. In cases where the cells are not accessible by needle, a longer tube called an endoscope may be inserted into the body with forceps attached for acquiring the specimen. Biopsy analysis is used in diagnosing cancer and muscular dystrophy.
