By Mayo Clinic staffA 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.
