Oh yes I forgot to add that. I have been followed up every 6wks since my 3 month CT scan. These include a visual check of my mouth and of the base of tongue with an optic endoscopy via the nose, and a physical external examination of my neck. I expect that the time interval will increase once past one post treatment. I have also been told that I wont get another scan unless there are indications of any concerns, for the same reason that they want to avoid unnecessary further radiation.
