Needle biopsy
A biopsy is a sample of tissue taken from the body for more detailed examination. When initial testing shows that an area of tissue in the body is not normal, a doctor may recommend a tissue sample for a more accurate diagnosis. Doctors may call an area of abnormal tissue a lesion, tumor, mass, or cyst.
