Hi MJR.
My dad died of prostate cancer 8 years ago, aged 88 years, although it was never recorded on his death certificate.
During the last month of his life I contacted Macmillan nurses. They were fantastic. As I recall, if they deem someone is only likely to survive a further 3 months, they can be be moved, at no cost, to a hospice/nursing home for palliative care.
My dad wanted to die at home.
Unfortunately, his condition drastically deteriorated, to the stage where I couldn't even get him to have water. I was forced into asking him to be moved. Me and mum, were waiting for transport to collect him, when he peacefully passed away.
My heart goes out to you. All I can suggest is that you continue to show your dad, how much you love and care for him.
