2nd time at colposcopy clinic

Hey all. My first post.
I was on 6 monthly smears, had to go in and get biopsies taken, I had cgin 3. Went back and had the treatment to burn away the cells.
Recently went back for check up smear, the first one after having treatment and got a letter today saying more changes. Is it likely the cgin is back? Do they just do the same treatment again if it is? I’m not overly worried as I know what to expect but just want to know if it all goes the same process? Thanks T xx

My first smear after 1a1 cancer came back as abnormal again..... see history below.
