Biopsy is a procedure where several pieces of prostate tissue are removed for cytological analysis by microscopy to determine whether the tissue is benign or malignant.1. What is a prostate biopsy?
The prostate is a gland that exists only in men. The prostate gland is located below the bladder and surrounds the ureters. The prostate gland plays a role in the production of semen.
Prostate biopsy is a procedure in which the doctor takes a tissue sample from the prostate gland to take for pathological examination (examination under a microscope) to determine the presence of cancer.
Prostate biopsy is indicated when screening results (blood test or rectal examination) suggest the presence of prostate cancer.
