Overview

A prostate biopsy is a procedure to remove samples of suspicious tissue from the prostate. The prostate is a small, walnut-shaped gland in men that produces fluid that nourishes and transports sperm.

During a prostate biopsy a needle is used to collect a number of tissue samples from your prostate gland. The procedure is performed by a doctor who specializes in the urinary system and men's sex organs (urologist).

Your urologist may recommend a prostate biopsy if results from initial tests, such as a prostate-specific antigen (PSA) blood test or digital rectal exam, suggest you may have prostate cancer. Tissue samples from the prostate biopsy are examined under a microscope for cell abnormalities that are a sign of prostate cancer. If cancer is present, it is evaluated to determine how quickly it's likely to progress and to determine your best treatment options.
