WHAT IS A PROSTATE BIOPSY?
A biopsy is a procedure performed to remove tissue or cells from the body for examination under a microscope. A biopsy of the prostate is a process in which the samples of the prostate gland tissue are removed with a special biopsy needle or during surgery to determine if they are cancerous or have other abnormal cells. The diagnosis of prostate cancer is confirmed only by a biopsy.
