A prostate biopsy has a slight risk of causing problems such as:
- Infection. This is more common in men who have undiagnosed prostatitis. Usually, taking antibiotic medicine before the biopsy prevents an infection from developing.
- Bleeding into the urethra or bladder. This can cause a blood blister (hematoma), an inability to urinate, or a need to urinate often.
- Bleeding from the rectum. If you have a transrectal biopsy, you may experience a small amount of bleeding from your rectum for 2 to 3 days after the biopsy.
- An allergic reaction to the anesthetic medicines used during the biopsy.
After the biopsy
Call your doctor immediately if you:
- Have heavy bleeding or bleeding continues longer than 2 to 3 days.
- Have increased pain.
- Have a fever.
- Are unable to urinate within 8 hours or have blood in the urine for longer than 2 to 3 days.
A prostate gland biopsy is a test to remove small samples of prostate tissue to be examined under a microscope. Results are usually available within 10 days.
If cancer cells are present, a grade (Gleason score) will be given, which your doctor will discuss with you. The Gleason score is considered a tool for predicting how aggressive the cancer is.
What Affects the Test
Reasons you may not be able to have the test or why the results may not be helpful include:
- The biopsy may not contain enough tissue to make a diagnosis.
- A chance that a cancer may be missed since the biopsy takes a small amount of tissue.
