Good news!
As I have said before, I asked two oncologists (one the top PCa doctor at the Royal Marsden) and my own surgeon about ‘super-sensitive assay”, i.e. PSA testing to lower than 0.1, and they all concurred that it’s more trouble than it’s worth except in a few rare cases.
My own hospital only tests to 0.1 anyway, so <0.1, ‘undetectable’ is a result.
Chill out for another year, that’s if you can in the middle of the plague pandemic.😷😷😷
Best of luck.
Cheers, John.
