Punch biopsy without having had a smear? Scar tissue?

Hi, I had 2 punch biopsy on 20th Nov. I was initially referred just based on some abnormal bleeding, I haven’t had a smear since 2013. I have had 2 treatments in the past for CIN 3. The doc said the white area shown when I had the colposcopy could be scar tissue? I’m getting really anxious! Any advice or similar stories would be gratefully heard!!! I don’t understand why they didn’t just perform a smear? It worries me they habve seen something and are just jumping straight on it?
