My grandma was diagnosed with bowel cancer sometime last xmas(we didn't know and she didn't want us to know) however when we did find out we discovered from her gp she had six months at most and this was at the beginning of August. She has deterioted  a lot and fell down the stairs on Boxing Day as she thought her stair lift was at the bottom. This has resulted in a fractured pelvis a bleed on her brain and lung. What's worrying me most is the absolute confusion she has which has steadily got worse over the last week. Today in the hospital she thought we were other people and has no concept of time. Is this related to the cancer as we have no joy from the junior doctors that are around as every day I see her this seems to be getting worse, the doctors think the bleeds are from the fall and the confusion started before this
