Dear dough boy:
Sorry you have to be here but welcome. You will find lots of caring and helpful folks on this forum.
Your question is the age old one that has been discussed and debated many times here. May I suggest you scroll back through some of the old threads and you will see lots of info on both sides of the equation.
Without repeating too much, let me just say that there is long term evidence that shows the cure rates are similar for both surgery and radiation. However, many of us radiation patients have concluded that the side effects are considerably less onerous for those choosing radiation than surgery. If quality of life is important to you I suggest you Google "New England Journal of Medicine Quality of Life Study". That will provide a pretty even handed review of what to expect 2 years out...in particular for sexual functionality for example you will see that 43% of surgery patients reported "overall sexual problems" vs. their baseline of 12% pre-treatment. The same stats for OLDER brachytherapy patients was 30% vs. a baseline of 18%. You do the math...
Feel free to cut and paste the link in my signature if a first person brachytherapy journey is of interest to you.
Good luck and please keep us up to date on your progress,
