"I am awaiting second round of chemotherapy, but there are no beds"

I am a cancer patient awaiting a second round of chemotherapy. I have been told from my doctor that it is medically essential that I am treated on exactly this date, as it is a certain amount of days after my previous treatment. However, I have been told that there is no available bed therefore I am having to wait until a bed becomes available.

The issue as I understand it is that the cancer ward cannot 'ringfence' the bed and has no way of guaranteeing a bed, despite it being medically essential that I receive treatment today.
