Thanks Roger, I'm sure he will be fine with things hopefully under control, we went for his twelve month scan this morning so fingers crossed. There are lots of people far worse off.
Cancer seems to be all over the place these days, a friend called me a couple of days ago to say he had been diagnosed and during the course of my job I speak about it most days.
When my father in law died it was quite rare to hear of it. I know nothing about the causes but I can only assume that it is the influences of our modern lifestyle (or at least they don't help).
