Biopsy results

Hi ladies, I posted just over a week ago as I has severe changes on my smear, went for a colposcopy last Tuesday and just had my biopsy results today. 


CIN 3 detected. Booked in for them to take it out on the 9th April. The doctor said I would have a D&C aswell. Is this usual? 


I am in Germany with the British army (husband serves not me! Lol) so wasn't sure if things were different here? I suppose I'm still worried that there could be CC that they haven't seen that might come back when I have the procedure done. she told me a bigger biopsy but also mentioned a loop so I'm not sure if it's a cone biopsy or a lletz procedure I'm having done, there's abit of a language barrier. 


Thank you :)
