Hi all, just got back. It's been a very long, but ultimately, great day.
Bottom line. Nothing in the lymph-nodes. All clear, tumor removed.
Mom had a tough time coming out of the anesthesia, after the operation, but other than that everything went great. The doctor was all smiles and said "She is going to be fine!"
I am beat and will write more later, for now I just want to thank each and every one of you for your thoughts and kind words. I know that the positive energy you all put out there did the trick.
