[|Human|] My Mom has Metastatic Brain Cancer.  She is in a nursing home and is in alot of pain in her head and neck.  We are trying to stay ahead of the pain.  She is also not mobile and sleeping alot.  Her family lives very far away.  How will I know when it will be time to tell them to come and stay with their father when the end is near?  Will there be signs I can look for?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. It depends on type of cancer.  It is metastatic, so it is in last stage that is sure.  However, life expectancy depends on type of brain cancer grade of cancer.  In most of the cases' life expectancy is not more 6 months. 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.
