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

A biopsy is a procedure used to remove small samples of tissue from the body for examination under a microscope. It can be done using a needle or a surgical instrument. The goal of a biopsy is to identify and diagnose any abnormal cells in the tissue sample. Biopsies are usually performed to determine if a tumor or other abnormal growth is present in the body, or to check for certain types of infection.
