[|Human|] My 88 year old Grandfather has stage 4 jaw bone cancer, it has spread to his Lymph nodes and his lungs, we also believe up to his brain. He is showiing signs of dementia and has only eaten a couple bites of food today and yesterday, he is not drinking very much fluids. He is sleeping a lot and very difficult to wake up. What would say hiss life expectancy would be? The Drs are kind of dancing around this question and we really need to know, he has 3 children out of state that we need to let know
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  He has jaw cancer with metastasis in brain and lung.  It is stage 4 cancer.  No treatment will cure the disease.  His age is also not favorable for chemotherapy.  So life expectancy is very short.  It varies from case to case but not more than 3 months in general.  Sorry to say but it is fact. Consult your doctor and plan accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
