Greetings, Bill. Welcome to this site and to the club that no one wants to belong to. You have many options and most importantly, you have lots of time to make a good decision. You will hear from many here that have elected many different options and I am convinced that the option that is right for one guy is not right for another. There is not such thing as the only "right" answer. You have to find the one that is right for you. I am convinced that your doctor - guided by you asking good questions that you will ask because of the detailed research you have done - is the right person to help you make the final decision. By doctor, I tend to think of your primary urologist - not a surgeon or a radiation doc or a doc who does mainly seed implants or one of the other options.
In my case, my urologist (who doesn't do surgery or radiation - he specializes in impotence) after doing my biopsy, sat down with my wife and I and went over options. Based on his recommendation I chose surgery - mainly because of my age. You are younger than I was. However, there are younger guys who end up doing radiation or seeds and do well. You have to find the option that is right for you.
Bottom line for me - surgery has a big plus and a big minus. The minus is you will most likely have more side effects (impotence, incontinence, no ejaculation). The big plus for me is knowing where I stand and the fact the prostate with the cancer in it is gone. Absolutely no guarantee that I won't have to have some followup treatment sometime, but all indications are that my cancer is gone. I am one of the very, very fortunate ones that didn't really have to deal with incontinence (dry at day 3) nor deal with impotence (yes, I take a pill 2 times a week but no big deal).
Find the right choice for you, make your decision and go with it. Never look back - only forward. As our friend Dale said on another thread just this morning, we all plan to be here debating the issues and supporting each other 10 years from now. You have found a group of guys (and gals) who have been there, done that and are interested in helping you in any way we can. Please keep us posted on how things are going. David
