Carrying for chemo therapy patient?

My mom is soon to begin a chemo therapy. I have a general idea how it is going to be, but not sure. She is in her seventies. She has mantle cell lymphoma which is incurable, as her dr. said, anyway, he recommended rchop, a very aggressive therapy, that will only help with growing cancer that is on her kidney. Nothing nice to hope for, as she is in her 4th stage.
