"Left hi and dry"

My elderly aunt has been admitted for a broken hip. She was told she also has lesions and then riddled with cancer. She refused the op because she was scared. Nobody seems to be singing from the same hymm sheet and feel there is no communication from anyone in the hospital. She has not drank for days and not drip to hydraye her. I feel for the staff as they are left running round and not being able to take time with the patient's. The staffing is near none existent and that is not a dig at the one that are there as they do their best. I am at a loss to find anyone to get answers as to why one minute she doesnt have cancer and the next she is riddled. Regards frustrated
