I really feel for you, this nightmare is such a difficult one to live with ... I understand that the cervix is only a certain length and so I guess eventually there comes a point when they have to look at removing it to treat the abnormalities. Very very tough, and challenging on so many levels.
The lady on here who I chatted to at the time she had her hysterectomy had everything tested and they said they removed all the abnormality. She was having a vaginal vault smear 6 months later, and hopefully everything worked out ok for her. Hopefully it will do for you too.
Take care and please feel free to message me anytime if you ever need to chat x
