Why it's done

A prostate biopsy is used to detect prostate cancer.

Your doctor may recommend a prostate biopsy if:

  • A PSA test shows levels higher than normal for your age
  • Your doctor finds 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
