CIN 1 questions

Hello, 

Just wanted some advice please. I’m 22 and been told I have CIN 1 as well as a cervical ectropion. I was originally referred for a colposcopy because the doctor saw the ectropion, and then biopsy were taken at the colposcopy. Which came back as CIN 1. I don’t really know much about CIN 1, I’m told it can go by itself. However in a couple of weeks I am going for cryocautery to treat the ectropion. Just wondering whether this will help treat the CIN 1?

and also if I have CIN 1 does that mean I have HPV? Or is it possible to have CIN 1 without having HPV?

sorry for all the questions,

many thanks in advance
