If your PSA numbers are correct I think some posters are not seeing what I see.

.02 and all your PSA tests would be considered non detectable with the traditional PSA test which is >1

If you are using the ultra sensitive psa test then each lab designates what is considered undetectable. You posted undetectable does that mean your labs are saying the numbers you posted are undetectable? Are you on any hormone treatments and did the end and you are seeing a extremely small increase each time? Is that correct.

I did not have RP nor hormone treatments but what I read is your PSA test are at the undetectable numbers but again not familiar with your lab and what they use as undetectable when using ultra sensitive test.

Not sure I help here but tried.
