My doctor wants to take a biopsy of my prostate gland. What is a biopsy?

A biopsy is a procedure in which tissue samples are taken from an organ or other body part for examination under a microscope. The sample is usually taken with a needle, but it can also be taken with a small surgical instrument called a punch biopsy. The goal of the biopsy is to determine whether there are any abnormal cells present that could be cancerous.
