My friend has stage four brain cancer . He will no longer recieve treatments . It has been 15 months since he was diagnosed. He has a few typical symptoms of brain cancer......sleeps alot, memory loss , confusion, vomiting. How much longer do you think he will live? I don t know what type of cancer he has. Thank You Jeanette
Hello Jeanette.  Every individual is different, and every cancer is also different, as such, I am unable to tell you how long he will live.  Everything I could tell you would be a guess on my part and would not be beneficial for you. Be well,
