Why it's done
By Mayo Clinic staffA prostate biopsy is used to detect prostate cancer. Your doctor may recommend a prostate biopsy if:
- Results of a prostate-specific antigen (PSA) test are higher than normal for your age
- Your doctor found lumps or other abnormalities during a digital rectal exam
- You've had a previous biopsy that was normal, but you still have elevated PSA levels
- A previous biopsy revealed prostate tissue cells that were abnormal but not cancerous
