You may have a biopsy after an MRI scan. Your specialist should explain the risks and benefits of having a prostate biopsy and give you time to decide if you want to have a biopsy.
During a biopsy, small amounts of tissue are taken from the prostate using a special needle. The samples are sent to a laboratory, where a specialist doctor called a pathologist looks for cancer cells in the tissue.
There are two main types of prostate biopsy:
- transperineal (TPUS) biopsy – the needle is inserted through the skin between the anus and the scrotum
- transrectal (TRUS) biopsy – the needle is inserted through the rectum.
A transperineal biopsy is most commonly used. It is normally done under general anaesthetic. The specialist passes a small ultrasound probe into your back passage (rectum). An image of the prostate appears on the screen, which helps guide the needle into place.
A biopsy can be uncomfortable. After the procedure, there may be a small amount of blood in your urine or bowel motions for a few days, and you may see blood in your semen for a couple of months. It usually takes 1–2 weeks for the biopsy results to come back.
