This is a confusing topic. For as many searches as you do on the topic, you find as many opinions.
Nomograms are a statistical statement. The studies are an observation of the sample at hand. Stats say that heads or tales is a 50/50, however when you do it 100 times, it may be 30/70, or 70/30, or it may land on the edge once.
It is true , PT3NOMO is not the best diagnosis statistically, but you will find many guys here who are beating the odds. The why is the tricky part. Every trial may come up with a different conclusion based on what they are studying.
For me, it has become a personal choice of when I want to pull the radiation trigger. So far, I figure I have potentially extended my longevity by a couple of years by waiting, if I can expect 10 yearspost radiation, which may be an entirely bogus belief and number. With .01 PSA, I just am going to wait.
Oh, and welcome to the forum.
