Harmone treatments following Cyber Knife...Good or Bad

mrd

I am 71 and had Cyber Knife treatment (5 Treatments) 3 months ago...my Urologist wants to continue to give me a harmone shot every three months totally four after the last one. One was given to me a month prior to Cyber Knife; I have read several negative comments about this Urologist's commitment to giving me these shots; I have read that medical studies have found no value with continuing with these shots after cyber knife and that they have very bad side effects.
