What Is This Test Used For?
This test helps doctors evaluate suspicious areas in the prostate, such as those detected during a digital rectal exam (DRE) or imaging studies. It may be recommended if you have symptoms like urinary changes, pain, or if screening tests (like a PSA blood test) suggest an abnormality.
How Is the Procedure Performed?
A healthcare provider will guide a thin needle through your skin and into the prostate using imaging (e.g., ultrasound or MRI). A small amount of tissue is collected for examination under a microscope. You may feel discomfort but should not experience significant pain. Local anesthesia is often used to minimize discomfort.
What Happens After the Test?
After the procedure, you may feel mild soreness or discomfort for a few days. You’ll need to avoid strenuous activity for a day or two. The collected tissue samples are analyzed by a pathologist to check for abnormal cells, including cancerous ones.
What Does the Result Mean?
Results can indicate normal tissue, benign conditions (like inflammation or benign prostatic hyperplasia), or cancerous cells. Your doctor will discuss findings with you based on the full report, including any additional imaging or tests needed.
Reference range
Adult: 136-145 mmol/LN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is critical for diagnosing prostate cancer early, when treatment options are often most effective. It also helps rule out non-cancerous conditions that may cause similar symptoms. Early detection can lead to better treatment plans and outcomes.
Short name
Prostate Biopsy (Image-Guided FNA)
Frequently asked questions
Will I Feel Pain During the Procedure?
Results are usually available within 1–2 weeks after the test. The pathologist examines the tissue samples under a microscope, which can take time depending on complexity. Your doctor will contact you once findings are ready.
