Are they 100% sure?

Hi,

I got my results back from my LLETZ biopsy last week, the letter confirmed CIN 2 and 3 and said that they ‘think’ it was all removed by the LLETZ. I have to go back for a smear in Feb, I just wondered if anyone had ever got the same news but then had more issues at the follow up smear or is it pretty much definite that everything is fine and dandy, im still really anxious I don’t know why! Also with the smear test follow up is it more intense than the first as I was told my cervix is very small and hidden so I want to be sure they take cells from as much of it as possible considering my first smear test they didn’t take enough at all!
