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.

The procedure is performed by a doctor who specializes in the urinary system and men's sex organs (urologist).
