What Should I Expect From a Prostate Biopsy?

Medically reviewed by Monica Chatwal, MD.
A prostate biopsy may be recommended if the results of a digital rectal examination (DRE) or prostate-specific antigen (PSA) test suggest that prostate cancer may be present. The most common approach for performing this diagnostic test is transrectal, in which a needle is carefully passed through the wall of the rectum to retrieve a prostate tissue sample.
What to expect during a prostate biopsy
If a transrectal prostate biopsy is recommended for you, here’s what you can expect:
- You will be asked to lie on your stomach or on your side with your knees pulled up to your chest.
- After cleansing the area and applying a gel, a physician will gently guide a thin ultrasound probe into your rectum.
- Using the probe, the physician will generate sound waves that will be used to create detailed images of your prostate.
- Guided by the resulting ultrasound images, the physician will numb the appropriate area and then place a spring-propelled prostate biopsy needle in the proper position.
- Once the area has become numb, the physician will use the needle to obtain several thin, cylindrical sections of prostate tissue for evaluation under a microscope.
- Each time the needle retrieves a tissue sample, you may experience a brief pinching sensation.
- The entire procedure will likely take about 10 minutes to complete.
What to expect after a prostate biopsy
After your procedure, you may have mild tenderness and see some light bleeding from your rectum. You may also see a small amount of blood in your urine, stool and semen. You may be advised to avoid intensive activities for 24-48 hours, and you should call your physician right away if you experience difficulty urinating, worsening pain or heavy bleeding.
