For what it's worth Tony...
My parents went through exactly what you are going through with myself.
Without waffling on too much, I had cancer in the bowel and spent my first 2 years in hospital mate and had many of nights the doctors told my parents, pray tonight as we believe he won't make it through the night, say goodbye, etc.
From the stories I've read about him being a strong fella and seeing his old man in person as a stubborn head strong individual, he'll get through it old mate![]()
