I think it’s entirely appropriate that your Dad should decide whether or not to endure ‘treatment’, as in these late stages they tend to be ‘kill or cure’. But if hormone therapy could help, why not? I don’t suppose he would be too bothered about growing ‘moobs’ if it provided some pain relief.
It is good that a hospice is involved, and let’s hope they can do a decent job with him in terms of palliative care.
Best of luck to you all.
Cheers, John.
