Take your time and ask alot of questions before you decide on the best treatment for you. Getting 2 or 3 opinions is not a bad idea as well. You may find a variety of recomended treatment plans. Studies show that all of the various treatment options are similar when looking at 15 year survival rates. What these studies do not provide is how the various treatments affect your lifestyle. I would ask your urologist and radiation oncologist what are the chances of recurrence. From the studies that I reviewed the various forms of radiation have a 5-10% chance of recurrence for low or intermediate risk patients. I have not found a recent study on recurrence rate for surgery, but if you google recurrence following prosectomy it can range from 20-40%. These numbers may not apply to you because I could not determine what risk category made up these numbers or if they were prior to robotic surgery. So it is good to ask this question. Also consider what side affects you are willing deal with and possibly live with. Surgery frequently is followed by some incontinece that may or maynot resolve, looking through the comments you will find many questions on this. Radiation may require you to take Flomax for a few weeks but no incontinece. Radiation and surgery can result in erectil dysfunction, generally this occurs following surgery and with radiation it can develop over 3-5 years. Consider the recovery rate and how this may affect you. Most men that have radiation can continue to work while they are being treated and maintain an active lifestyle, surgery requires a longer recovery. It was mentioned that with surgery the pathologist can determine your risk of recurrence or spread, this can also be done with genomic testing the biopsy samples. Ask your doctors thier opinion on this, you may find a range of opinons.
