I think losing his taste buds is the least of his problems! This scenerio sounds very familiar ,my friend was in the same position with a very high psa ,his treatment was similar to what you have described, he took the treatments and he now has cancer in his lymphnodes and in his bone marrow! They told him he was receiving the most updated treatments and techniques targeting only the prostate with the radiation and that he was a good candidate for complete remission! A simple lie that will ultimately cost him his life!
Sorry for this negative note ,but if one takes these treatments there is NO guarentees whatsoever of the outcome!
