It's been 1 year since GK and MRI shows AN is stable. My 16mm AN is now 12mm. I am feeling great and can now look forward to an MRI only once a year vs. the 4 I've had in the past year, yeah!!! I am a little confused however, as my Dr. said while the tumor shrinking was good he was more happy the tumor was moving "up and away" from my brain with less "brain stem compression". Huh?? I was not aware I had brain stem compression especially with only a 16mm tumor, didn't think that was a possibility with a small to medium AN. Am I missing something or did I misunderstand what MD said? Thank you for all the information and support I've received this year from so many wonderful people on this site.
