Wishing you lots of luck with the Ultrasound and I look forward to hearing how you are getting on.
Not sure if you have read up on the differences between CIN & CGIN but from what I understand, CGIN is the same as CIN3 only it is located within the glands rather than on the surface. CIN tends to stay in the one place but CGIN can skip layers.This is why it is tricky to detect and monitor.
My Colposcopy biopsy did say that I had clear margins and a lot of women take comfort in that but personally I couldn't stand waiting, worrying & uncertainty of it coming back so opted to get it all out.
I am waiting to hear back from my Histology on the actual Hysterectomy as I only had the Op on 18th July (and I am recovering well from that!) My Consultant (who is on holiday at the min)has re-assured me that they are not expecting any nasty surprises re cancer however they have in the past found more of those little rascals hiding in there when they remove it all.
6 months down the line I will have a 'Vault' smear to check all is ok in the Vagina and then I am hoping to put it all behind me..
The consultant may ask you if you're family is complete and offer a Hysterectomy which is a big decision for a lot of women... For me personally it was the best thing to do for sanity's sake and the surgery wasn't bad at all..
Again, this is just my story..I hear of a lot of women on this site that have had Cgin and got it sorted with Lletz & Cone Biopsy.
Sending you best wishes and positive thoughts.
