So I accidentally had another ultra-sensitive PSA test, this time at work (I had a screening done in order to get my Mutual of Omaha cancer policy benefit).

It was 0.08.  

My prostate oncologist released me from his check-ins, because I was consistently below 0.1 and he didn't believe in ultra-sensitive testing for someone like me.

To recap, I don't have a prostate, and I have been less than 0.1 since the end of radiation in 2007.  

In mid 2020, a test showed 0.02, the first time any number had registered for me. Then just over a year later, 0.05.  So that's when I checked in with a prostate specialist. They ran standard tests every 3 months which were all less than 0.1.  

So it would seem that it is creeping up, but very, very slowly. I calculated a doubling time of 28 months. That would put me over the 0.1 line within a year, if the trend continues.  If.

I'm not going to worry about it for now. If it gets to 0.1 then I'll contact the prostate oncologist again.
