I think cost benefit studies are a great idea, but the studies have not been finalled, and writers should watch what they say. This guy is not too bad but there is a group out there suggesting we drop PSA tests.
First off no doctor would rec watchful waiting for a person under 75, but they ALL suggest active surveillance, there is a big difference, including cost. I estimated my AS prgram with office visits, yearly biopsies, pathology checks and avodart was going to cost $3000/ year, most of it paid by me. This would be every year until eventually I drop the big one, so I did not see it as overall cheaper. It wasn't going to make it go away, just delay the final procedure.
The other thing, and this is why we need studies, at least from this board it seems there have been a significant number of guys who had worse than expected after surgery pathology, waiting probably would have killed them or at least driven costs trough the roof.
Last thing is with the high % of prostrate cancer, even a small percentage improvement equates to thousand of lives saved.
