My dad was told he had lung cancer in April and there was nothing they could do. Five months on he is still with us, they have told me he has brain mets and one has become a large tumour, he also has heart failure. My emotions are all over the place. He is in a hospice. One day I visit and he is asleep the whole day but another day I go and he is awake and quite jolly. He eats and drinks. I have gone today and they have said his breathing is laboured, but he seems the same to me, however the base of his finger nails have started to go a grey/blue. I get so confused with how up and down he is. Is this normal? Any advice would be so appreciated.
