Superhoop I had RT (37sessions to prostate&pelvis)with 3yrs Zoladex (plus nearly 2yrs on trial with abiraterone, enzalutimide, prednisolone). Firstly tatoo dots no problem whatsoever you dont even realise its done.
Personally, re HT, they suggest it for a reason, to starve the damaged cancer cells so they dont recover and I'd always go along with it. Side effects are a big nuisance and I had most of them, but its true that you do get over them given time. Think I had it in my mind that it wont last for ever, it could be worse etc and Knowing how it effected me I'do same again if necessary.
