[|Human|] My father was just diagnosed with stage IV lung cancer (adenocarcinoma) that has metastized to the brain. He is 78 and is in poor health. Hes a former smoker. Hes lost a lot of weight and chemo and radiation arent options. Hospice has been called to help us with him. I wanted to know what sort of time frame that I could expect? 6 months? 3 months? What would be symptoms that would indicate end of life? I feel helpless.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. Your father has stage 4 lung cancer. It has very poor prognosis. Symptom depends on spread of cancer. He has brain metastasis so respiratory failure and stroke or convulsion can be there. Life expectancy is not good. It is generally less than 6 months, but it varies from case to case. Hope I have answered your question, if you have any doubts then contact me at bit.ly/ Chat Doctor. Thanks for using Chat Doctor. Wish you a very good health.
