Hi Beebee.
My husband was absolutely adamant that he was never going to have chemo, from the moment he was diagnosed with advanced PCa. Unfortunately he was one of the unlucky ones and did not respond for long to any treatment. But when it came to the point when chemo was the next option he very reluctantly agreed (with tears in his eyes). I know everyone responds differently to different treatments but the chemo amazed us. He changed from lying in bed all day and barely eating, to going on 2 breaks to the New Forest where he was striding off into the forest with me trying to keep up! I clearly remember a picnic we had and he just kept eating and eating and eating! He went back to his part time job as a room guide in a stately home - so amongst large numbers of the public. Yes he had some days when he felt less well, but they were only a couple of days each cycle. He didn't even lose his hair (well not on his head anyway).
He had Abiraterone after the chemo which unfortunately did not work for him. But I am so grateful now for those few months of chemo which bought us some normality and some happy memories. So I guess all I'm saying is not to dismiss any treatment out of hand....
Wishing you and dad all the best whichever route you choose
