I have to agree that they should have mentioned that you had a positive lymph node. Hopefully, you will be armed w/ written questios when you see your surgeon for your follow-up visit. I had 19 0f 21 lymph nodes positive. Don't be surprised if they tell you that you are going to need treatment because of the one node being positive. Just remember that you want to do everything you can to beat this.
My bil is an obgyn. I can't tell you the number of times he has had to postpone or delay an elected surgery for one of his patients because an emergency came in and needed the OR. I can imagine how your anxiety increased while you had to wait all of that time.
Please keep us updated.
