Having a peg tube fitted isnt really surgery,robin had his done under light sedation and didnt remember a thing,it was over in a few minutes and was invaluable to him right up until the very end as he had all his medication via his peg which meant it got into his system much quicker,it also meant he never had to be hydrated in hospital or worry about the pain of eating and swallowing.
Dont ever underestimate the radiotherapy it is tough!!!!
