My grandfather is 73 years old and has battled cancer for the past 15 years. He was cancer free for many of those years that I've been till about three years ago it had came back. He has had many surgeries and many treatments since it has returned. But with this last discovery of cancer that has spread to multiple locations so chemo is the only option. He's been on chemo for the past month he has been experiencing a lot of pain. He has lost a lot of weight. He has been getting frustrated and angry more often which is the opposite of his personality. He does not want to eat anymore and just wants to sleep. He is not in a hospice facility he is at home with my grandmother. Because of his recent actions of him not wanting to eat and just wanting to sleep more my question is, "this the beginning of dying?" He has stated that he doesn't want to be here anymore but I'm not sure if it's just the pain that's talking or if it's a real thing. If you guys could help I would appreciate it. Thank you.
