Understanding PSA

Your PSA level is above four ng/ml. In younger men, this is usually considered to be a worrisome level. However, your PSA level may be normal for someone in your age group.

Speak with your doctor about options for follow-up, including

  • referral to a urologist (prostate specialist)
  • repeat testing in 3-6 months to make sure that your PSA level is not rising by measuring your “free” PSA level — This special way of testing your PSA level may help to decide if a prostate biopsy is needed. High levels of free PSA are reassuring, while low levels are worrisome for cancer.
