No. The only side effect he has is going to the bathroom a little more often (no diarrhea). No rash, blood, or pain so far. His doctor is a bit stunned.
That is brilliant, I'm so pleased to hear that the side effects are so small.
I worked with a 30 something engineer who developed testicular cancer and he used to travel 5 hours to Houston for treatment, staying for a week or so at a time. Very difficult for him and his young family but he was cured, and that was over 15 years ago that he was given the all-clear.
