A biopsy is the removal of a sample of tissue or cells so that they can be examined by a pathologist, usually under a microscope. A specialist trained to examine a sample of tissue for signs and extent of disease under a microscope is called a pathologist.
A prostate biopsy is a procedure to remove small samples of prostate tissue to be examined under a microscope. See an illustration of the prostate gland. For a prostate biopsy, an ultrasound probe is inserted through the rectum ('transrectal ultrasound') and needles passed ('transrectal biopsy'). The biopsy samples are examined under a microscope for cancer cells.
