My dad has been under going tests, and had several biopsies of his colon, his last was 2 weeks tomorrow. In the post today, he received a letter asking him to come into a clinic tomorrow at 3:15pm, but more worrying was, the letter stated,  please bring someone who can support you in clinic. The local hospital have a policy that you must attend by yourself unless under 18yrs. 

Am I reading to much in to this??
