CIN3 and Colposcopy

Hi Everyone, 

New here and I am really struggling, tralling the Internet trying to find the information I am after! 

I am 32 and recently had my smear, the letter can back with HPV positive abnormal cells high grade severe dyskaryosis - CIN3.

What I am trying to find out to put my mind at ease, is has anyone had the same and did it turn out it was cancerous! and what is the odds of it being cancerous? 

My colposcopy is booked in for the 20th April. 

Any information anyone has would be great. 

Thank you so much x
