Hi there 

Sorry to hear about your poor dad .

My dad died in Sept after being diagnosed 2 months before , he was treated poorly by the NHS , he had Osephageul cancer stage 4 , he had chemo way too late , it made him 10 times worse he died a week after his first chemo . The  best thing the palliative team did was to put him in a hospice, the hospice was superb, so I suggest if your dad starts to really suffer , don't hesitate to put him in your local hospice , these places make our NHS hospitals look like third world hospitals . Your dad will get the care he deserves in a hospice .

Good luck too you
