Prostate Biopsy

Cancer occurs when abnormal cells form a tumor (a lump of cells that grow uncontrolled). If the results of your exam and tests lead your doctor to suspect prostate cancer, a core needle biopsy will be done. A thin needle is used to remove small samples of prostate tissue. These samples are checked for cancer.

Taking Tissue Samples

A biopsy takes about 15 minutes to 20 minutes. Before it starts, you may be given an enema or suppository to clear the bowels. Antibiotics are given at least 1 hour pior to the biopsy. During the procedure:

  • You will be given antibiotics to prevent infection.

  • You may be given a sedative, local anesthetic, or pain medication.

  • A small probe is inserted into the rectum as you lie on your side. An image of your prostate can then be seen on a video monitor. This is called a transrectal ultrasound (TRUS).

  • With the TRUS image as a guide, your doctor uses a thin needle to remove tiny tissue samples from several sites in the prostate.

  • These tissue samples are sent to the pathology department. They are looked at under a microscope so a diagnosis can be made.
