Confused about results of Lletz

Hi, I have today received a letter from the hospital following up from an extended Lletz, colposcopy and biopsy last Thursday and I am confused about what it says and was wondering if anyone can help.
(Background) Following a smear I was found to have high grade GCIN and HPV. I went to have a colposcopy and they had trouble ‘seeing’ what they wanted to so referred me for Lletz, biopsy etc under GA. This was all quite quick as I have also quite recently had breast cancer.

The letter I have states the colposcopy I had under GA reveals I have no CIN, they could only take a few biopsies because the endometriem was very thin. It says they will write to me with the results and a follow up plan, but I am confused when it says there was no CIN. No mention of GCIN.
Can GCIN just disappeared in a matter of weeks or am I being a wally?

Thank you
