Is a PSA of 0.02 considered undetectable after radiation?

Thank you for sharing this question. Many people ask whether a PSA of 0.02 is undetectable after radiation, and the answer can depend on the lab's testing range and each person's situation, so the care team who ordered the test is the best source to confirm what the number means for the poster. Writing down questions for the next appointment, such as what PSA level is expected and how often it will be rechecked, can help make that conversation easier. Others in this prostate cancer community may also be willing to share what they learned about PSA results after radiation treatment.
