Why it's done

By Mayo Clinic staff

A prostate biopsy is the main method 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's normal, but you still have elevated PSA levels.
  • A previous biopsy revealed prostate tissue cells that were abnormal but not cancerous.
