My mother had a "poop"bag, and that helped most of the time, but then we all were in school and mom thought it would be best if she stayed in the hosptial so we didnt get to see her, but she slipped into coma's most of the time, she was out of it, because she was on moriphine, the doctors made sure she was pretty much pain free, she really lost allot of herself at the end, she didnt remember anyone, or anything, sometimes it came back to her who we were, but not very often, she couldnt walk or talk or anything for the longest at the last six months of it, she only had it for 2 1\2 years so when it hit that we knew about it it was hard hitting, when the doctors went in and started doing thier surgeries and chemo is when the cancer started to do its spreading and it spread everywhere, so it really just depends on where it is with your grandmother right now and where its going to. I hope your god takes her with peace and grace and speed in your and his time
