he has had a camera down throat, chest xray and ct scan, but no one has really explained and he is so laid back he forgets to ask! was packed off to doctors after much nagging because of hoarse voice and apparently one vocal cord isnt moving, but we dont know why. was told they would look for cancer (heavy drinker and smoker) but noone has mentioned seeing any tumours. cant find anything on net so help appreciated. tia
