Abnormal cells

Hi, in April this year I needed a colonoscopy and biopsy taken as I had high risk hpv they said I had cin 2 was found I then had a letz procedure done apparently the abnormal cells were removed, I went to the docs last month for my smear (6 months later) there’s been no change in the smear results so I’ve been referred back to the hospital they said I need to have another colonoscopy (I think I’ve spelt it right) and more biopsy’s will need to be taken I’m worried sick my hospital appointment is next week I’m scared and worried it’s cancer
