Lletz results

Hey All,

I just had my lletz today and am now waiting for my results after having a colposcopy and biopsy results came back CIN 3

The results will take 6 weeks apparently (Im a Brit living in Australia) but I'm a bit nervous about the results, how common is it that they find cancer higher up the cervix?

Also they had to give me a stitch when doing the lletz because they cut me with the speculum :/ I was under general anaesthetic has that happened to anyone else?
