A prostate gland biopsy is used to diagnose prostate cancer. In the most common type of biopsy, an ultrasound probe is inserted into the rectum in order to visualize the prostate. A hollow needle is passed through the probe and into the prostate several times, removing pieces of tissue for examination. After the biopsy, urine and semen may contain blood for several days.
