Dear smc:
Sorry to have you here, but welcome. Purgatory (David in SC) gave a nice, quick summary of your options and I agree. You DEFINITELY want to get multiple opinions from at least an experienced robotic surgeon (300+ procedures) and an experienced radiation oncologist. At your age and stats you have an excellent chance of cure and you may have the option of watchful waiting...however, if you choose that route, you need to be diligilent in terms of repeat testing. And, frankly, while the cancer may never get more serious, chances are that it will and that you will have to undergo treatment at some point.
As another poster noted, most of the research has obviously been done on older men since that's when the cancer is most often manifested. So...the statistics reflect that. However, the research I did showed that the cure rates for the most common treatments are essestially the same. But, if you choose surgery and the cancer returns, you can treat the cancer further with radiation. If however, you choose radiation first, then salvage surgery is very risky...I certainly would not do it...and you would need to go to the other options available.
Having said that, I chose radiation (seeds). I'm playing the odds that the cancer is cured and my SE's are non-existent so far and are likely to me less problematic than if I had chosen surgery. But...that's for MY particular case...you need to consult with your docs and make a decision for your own situation. If you are interested in my decision making process and progress to date with seeds, just go to "Tudpock's Brachytherapy Journey" on this forum.
Good luck and please let us know how things progress and what you decide.
