My dad was diagnosed with alzheimer's around 5 years ago and has been gradually declining since then. We've managed to keep him at home as I gave up work last year to come and live with my parents to help my mum care for him. Over the last few months he's occasionally had blood in his urine which the GP was pretty unconcerned about. Then recently he had a spate of about a week where it looked like he was peeing pure blood and clots. My mum managed to get a urine sample from him which was tested for infection but came back negative. However my mum is fixated with the idea that he has bladder cancer and spoke to the GP about this, without my intervention! He has referred my dad to the urology department and tests have been arranged for next Friday. These tests have to be done at our local (huge!) general hospital. My dad hates going out and following a glaucoma clinic appointment earlier this year we decided not to put him through any more appointments outside of the house. I have made it clear to my mum and family members that I think its cruel to my dad to make him go. Also, what is their hoped for outcome? Whatever the diagnosis he isn't going to be having any treatment other than pain relief. Incidentally, there's been no blood for the last week. Advice please
