What is a prostate biopsy?
The prostate gland is found only in males. It sits below the bladder and wraps around the urethra (the tube that carries urine out of the body). The prostate helps make semen.
A biopsy is a procedure used to remove a small piece of tissue or cells from the body so it can be examined under a microscope.
In a prostate biopsy, prostate gland tissue is taken out with a biopsy needle or during surgery. The tissue is checked to see if there are cancer or other abnormal cells in the prostate gland.
A prostate biopsy may be done in several different ways:
- Transrectal method. This is done through the rectum and is the most common.
- Perineal method. This is done through the skin between the scrotum and the rectum.
- Transurethral method. This is done through the urethra using a cystoscope (a flexible tube and viewing device).
Ultrasound is usually used to look at the prostate gland and guide the biopsy needle.
