Appointment following LLETZ

Hi, I have just joined and have a few questions. 

I'm 26, just had my first baby and went for my first smear a couple of months afterwards. It came back as high grade dyskaryosis, I was sent for LLETZ 4 weeks ago today and have to go for another appointment in a weeks time rather than the scheduled 6month check up.

I am aware that this could mean having to go for the procedure again or that they have found cancer. I was wondering IF it is cancer, what treatment would be and if it effects fertility?

We were thinking about trying for a second baby in a few years time, however I am worrying about whether or not this would be possible if I needed treatment? Of course I will see what they say at the appointment and take it from there, but any experience would be helpful :)

Thanks ladies!
