Yup, that's good. That is what is considered undetectable. I had my 3 yr. check up this past spring, and it was 0.003. As long as it stays there, we are pretty safe. I was told that if it is still that low at the 5 yr. mark, we should be good. I don't think once someone has any kind of cancer "cancer free" is never a certainty. My psa is good, but the incontinence continues. I still need diapers. Good luck in your recovery.
