Since I had radiation to being with, I obviously cannot answer your primary question. But I will make the following comments:
1. We had a thread on this very issue during the past week. The general conclusion, with which I agree, is that few if any patients will express buyer's remorse...sorta like being in love with a car after you buy it.
2. If you are interested in treatment comparison, might I invite you to read something I posted earlier today on the thread by new member SL. My post received the David (Purgatory) seal of approval which in all seriousness I appreciated.
3. There was a thread here the other day (now on page 4) that referenced an article on secondary cancers from radiation. Cutting thru all of the posts on the thread, the point of the article was that the overall risk of secondary cancer from radiation is less than 1 in 1000....and that the small risks was worth the benefit of the treatment. Risks of dying during surgery have been quoted as greater. But, personally, I would not seriously consider the small risks/events at the edge of the curve. I suggest you focus on the big three...cure, continence and sex.
4. One poster on this thread states that surgery has better results beyond ten years. That is not a proven fact. There are no random controlled studies comparing the effectiveness of surgery vs. radiation. There ARE a number of 15+ year studies done independently that show approximately equal effectiveness.
5. I think I mentioned this on your other thread but please consider a short drive to Sarasota. Dattoli is one of the best at radiation and he will certainly give you the perspective to make an educated decision.
Hope this helps.
