Prostate Biopsy
What is a prostate biopsy?
A prostate biopsy is a procedure in which small samples of tissue are taken from the prostate gland so that they can be examined under a microscope. The procedure is most commonly performed to investigate the possibility of prostate cancer, but it may also help diagnose other prostate conditions. A biopsy provides the most accurate way to assess suspicious findings from blood tests, scans or physical examination.
Why is it needed?
A prostate biopsy may be recommended if the prostate-specific antigen level (PSA) in the blood is higher than expected or rising over time. It may also be advised when a doctor detects an abnormal area during a physical examination, or if MRI or ultrasound scans show something that requires further investigation.
The procedure helps confirm or rule out prostate cancer and guides decisions about further monitoring or treatment.
What happens during the procedure?
A prostate biopsy is usually performed under local anaesthesia and may sometimes be combined with sedation. There are two main approaches, transperineal and transrectal. The transperineal biopsy involves passing the biopsy needle through the skin between the scrotum and the anus. The transrectal biopsy, which is used less frequently, involves passing the needle through the rectum under ultrasound guidance.
An ultrasound or MRI scan is used to guide the needle accurately into the prostate. Several small tissue samples, usually between twelve and twenty-four, are collected from different parts of the gland. The procedure generally takes twenty to thirty minutes and is performed as a day procedure.
What are the alternatives?
MRI scanning alone may sometimes be used to monitor the prostate and avoid biopsy if no suspicious areas are seen. Observation and regular monitoring may be appropriate for men with borderline PSA levels and no other risk factors.
Research continues into new blood and urine tests that may help assess cancer risk, but a biopsy remains the most accurate method for diagnosing prostate cancer when there is uncertainty.
Potential risks and after effects
A prostate biopsy is generally safe, but some temporary effects are common. Blood in the urine may occur for a few days, and blood in the semen is very common and may persist for several weeks. Mild discomfort or bruising may occur around the biopsy site.
Infection is a possible complication, and antibiotics are usually given to reduce this risk. A small number of men may experience temporary difficulty passing urine. In rare cases, a serious infection such as sepsis can occur and requires urgent medical attention.
After the procedure
Most people go home the same day after passing urine. Drinking plenty of fluids for the first twenty-four to forty-eight hours helps flush the bladder. Mild blood in the urine or semen is common and should settle gradually.
Antibiotics should be taken as prescribed. Strenuous exercise should be avoided for several days. Medical advice should be sought urgently if fever, chills or difficulty passing urine develop.
Follow-up care
Biopsy results are usually available within one to two weeks. A follow-up appointment will be arranged to discuss the results and any recommended next steps.
If cancer is detected, further tests or treatment plans may be discussed. If no cancer is found but the PSA remains elevated or concerning, additional monitoring, repeat MRI or another biopsy may be considered.
