My Mum is 87and has Kidney cancer for 2 years. It is not treatable and has spread to her back . She has received a small dose of radiotherapy to relive the pain and has had morphine. Mum is quite chirpy but physical changes are now very apparent and looks very poorly. She is a real fighter though and gaurds her independence fiercely. Given her age and medical condition can anyone give me an idea as to when we may be facing an end of life scenario? John
