[|Human|] Hi my Grand mother is 86 and has advanced lung, bowel and spine cancer she has chosen no treatment due to age she is losing her appetite, very tired but often says her chest hurts is this just a advanced cancer symptom? she takes medications am wondering if just a matter of time for her.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. But metastatic stage 4 lung cancer has very poor prognosis. At her age five year survival is almost negligible. And life expectancy is less than 7-8 months. Better to start palliative treatment for pain relief and nutritional support. Discuss end of life issues. In my opinion life expectancy in her case is less than 6-7 months.
