Has anyone heard statistics?

Hello! I found out in October I have AIS and scheduling my CKC for sometime here soon. I had my consultation with the Gyn Onc today and he said 90% of the time the CKC comes back with clear margins. He said if he we have to do a second CKC, chances are 95% clear margins. He didn’t seem concerned about the fact I want to delay a hysterectomy for having kids (I’m 31). Did anyone else hear similar or different statistics from the doctor?
