Mick, like everyone here, I wish you the best of luck and hopefully a quick victory over the big C and a return to rude health. Maintaining a positive outlook could be very critical to you so it is good to see you showing fighting spirit on here.
You will know from some of my postings that I am a very harsh, realistic actual fact person much of the time, so do not take offence at me telling you this. A couple of years ago, I lost a friend to mouth/throat cancer, who had been fighting it for five years. He had chemotherapy, all sorts of drugs and surgery, at one point not being able to speak because of throat surgery. After mouth surgery, his jaw had been wired so that he could not actually eat solids – living on (medically prescribed) protein drinks (and beer!). The terrible thing in his case was that he passed a couple of weeks after the oncologists had told him that they were going to un-wire his jaw because he was in remission. He never gave up until he was re-admitted to hospital a few days before the end. We have made massive advances in cancer treatments but to some extent, I still think you need a lot of luck. If one of our friends in the Emerald Isle can send you some of their luck, I am sure you would gratefully receive it.
