Hello Slamont and thanks for posting,

I'm afraid I don't know what percentage of people having a colposcopy need to have a cone biopsy, I wouldn't have thought very many do. A cone biopsy is done under general anaesthetic as a surgical procedure, whereas a more common treatment for abnormal cells is a Large Loop Excision of the Transformation Zone (LLETZ) which although similar takes away less tissue than a standard cone biopsy. Although both procedures can potentially have an impact on fertility, probably more so with a cone biopsy, this isn't at all common and you may not need to have either.  

Not everyone attending colposcopy will need to have any or immediate treatment;  some will have a normal examination and go back to regular screening, some may have a biopsy to decide if treatment is needed at a later date and the remainder will be recommended to have treatment at that initial visit. 

The cervcial screening programme invites women of an age when some could fall pregnant so it is used to working around pregnancies. I think it is up to you whether or not you want to carry on trying to conceive. Some women would rather have the colposcopy out of the way, but a colposcopy examination can be done during pregnancy.

You could try calling the colposcopy clinic to see if you can find out when your appointment will be, it might not be that far away, and take it from there.

I expect you have already read up on treatment for abnormal cells, but if not our website  explains the possible side effects and so does another charity website belonging to Jo's Trust. 

Give us a call if you want to talk anything over. We are around weekdays, 9-5 and the number to call is Freephone 0808 800 4040. 

Wishing you the best,

Julia
