Thanks for both replies above. I come to more or less the same conclusion from scanning the webs. The majority seems to be 5+ years old and counting. Most docs do not seem to want to stick heads out, for understandable reasons. Those who do, with the ones such as Dr. Scholz tend to provide low numbers, for understandable reasons.
One issue is they quote the clinical studies. The small print in these studies is their cut off point is PSA 0.5. But from some rare studies, and for practitioners such as Dr. Scholz,, their cut of is PSA 0.2. < 0.2 the survival rate for 5 and 10 year are about 85%.
It appears, and Dr. Scholz does articulate that, the outcome for those below 0.2 is very different. For under 0.1, Dr. Scholz's experience or opinion is more like 10 years.
So there seems to be a gap, and a fairly big gap .
