Having worked through my horror, then dread, then terror of the screening that I must undergo, I came to terms with it by remembering my father's illness that resulted in his death at the age of 69. His last few years were punctuated by one surgical procedure after another. If screening might enable me to avoid a similar course, then let's do it!
However, my procedure is a screening where there are no symptoms of disease. Covid has doubtless caused delays in dealing with people who do have symptoms, so a wait is to be expected.
A few things should be certain, I should get an appointment within three months of seeing the anaesthetist, and I should get at least a week's notice because I have some preparations to accomplish before the procedure itself
