All the scans in the world will still show you have PC. The color doppler will give you a more exact location, might indicate an EPE, but until you either have the walnut removed, and have the pathology done, you will not know any more than what you know now.
That may not be important to everyone, or some guys have medical reasons why they don't have surgery, some guys have chosen radiation based on side effects, simplicity, etc.
You can study this thing to death, analyze it, nomogram it, talk about it, etc., but until the pathologist gets that thing in his hands, you won't know much more.
Based on your inquisitive nature you have demonstrated here on HW, I really don't think you will rest until you get it into the pathologists hand. And then guess what, you still will have a hard time knowing what the future holds. A high percentage of men are "cured" by surgery. A good percentage of men have little problem with incontinence, a good percentage of men recover from the ED.
But no surgeon, radiologist, or faith healer can accurately predict precisely what your outcome will be. That is prostate cancer.
My advice is to begin a study of each potential treatment, and its curative rates, and potential side effects. Calculate your odds based on your own numbers, and pick one.
Once you pick it, stop, and go do it. You will drive yourself crazy with all of the what if games, if you don't. The odds are with you, no matter which treatment you pick statistically. You have got to slowwww downnnn, and be rational about this whole thing, and make your treatment decison.
Good luck, and stay with us here.
