Had mine done about 8 yrs ago at RCOG in Atlanta. Proceedure is a combination of seeds followed by radiation called "prostrcision". PSA has been 0.0 for about the last 6 years and minimal side effects. Going there is like a radiation vacation - this place is great. Check their web site
http://www.prostrcision.com/. They have published cure rate over 10 yrs in the Journal of Urology that are better then surgery at the gold standard for surgery at John Hopkins. Their tracking is extensive, with patents reporting psa levels and multiple page questionnaire on everything from side effects to sex. Eight yrs ago they did more prostate patents then the largest 3 major surgery hospitals. Doctors to patient talks each week on all aspects of the treatment / side effects / cure rates / changes in procedure, diet, etc lasting for well over an hr and the Doctors not leaving until all questions are answered. Activities for the wives. A place with free or minimal cost housing for your stay if needed. Patients really liked the housing and all become real friendly during their stay. I don't think you will find a better clinic in the world for prostate cancer.
You might want to ask your clinic or Dr if their cure rates and side effects are published and what they are over the years.
