Transperineal Prostate Biopsy
What is a prostate biopsy?
Prostate glands are only found in men and are about the size of a chestnut. The prostate gland is located just below the bladder in front of the rectum (back passage). Its function is to produce white fluid that becomes part of your semen. Small needle samples of tissue are taken from your prostate gland and then sent to be examined under a microscope for cancer.
Why do I need a prostate biopsy?
It is usually performed because the prostate-specific antigen (PSA) blood test is elevated, indicating a higher risk of prostate cancer. PSA is a protein produced by the prostate and detected in the blood.
A lump or abnormality during a digital rectal examination (DRE) of the prostate may be detected. A DRE is an examination where the doctor feels the prostate gland through rectum.
In the case of a known diagnosis of prostate cancer where further treatment is not as yet required, your urologist may require further information to ensure the cancer has not changed or plan for further treatments.
