What Is a Prostate Biopsy?
A prostate biopsy is a procedure in which small tissue samples are taken from the prostate gland using a thin needle. The samples are examined under a microscope to look for cancer cells or other abnormalities. A biopsy is the only way to definitively diagnose prostate cancer. The procedure is performed under ultrasound guidance to ensure accurate sampling from different areas of the prostate.
Why Is Prostate Biopsy Needed?
- Elevated PSA level — especially if PSA is rising rapidly or is significantly elevated
- Abnormal digital rectal exam — the prostate feels irregular or firm
- Abnormal imaging findings — MRI or ultrasound shows suspicious areas
- Family history of prostate cancer — increased risk warrants more aggressive screening
- High-risk ethnicity — African American men have higher prostate cancer rates
What to Expect
Before the Biopsy
Dr. Libby will discuss the risks and benefits. You may be prescribed antibiotics to prevent infection and asked to stop blood thinners temporarily. You'll receive instructions about bowel preparation and may be given sedation to help you relax during the procedure.
During the Procedure
The procedure is performed in the office or surgical center under ultrasound guidance. You'll lie on your side, and Dr. Libby uses ultrasound to visualize the prostate. A thin needle is advanced through the rectum or skin to obtain 12 or more small tissue samples from different areas. The procedure takes 15-30 minutes and causes minimal discomfort due to local anesthesia.
Recovery and Results
You can go home after the procedure. You may notice blood in your urine, stool, or semen for several days — this is normal and usually not concerning. Avoid strenuous activity for a few days. Pathology results typically take 5-7 days and will be discussed with you in detail by Dr. Libby, who will explain findings and recommend next steps based on the results.
