Yes, both GK doctor and radiologist were quick to point out that it is totally within the margin of error and could depend on the number of slices. I have noticed that during the last 2 MRIs, the MRI technician has been taking images of many more slices, I guess by now they know me too well, lol. So it could have something to do with the more detailed images. Vivian, I hope I haven't scared you, for sure GK has arrested the growth (it was a wacky 4 mm over 6 months before GK and almost negligible in two years post GK) and the tumor has shown necrosis. It is very common for ANs to grow slightly before stabilizing after radiation. If I end up in trouble, it will be because my AN was very large to begin with, so there is really no room for additional growth.
On another note, the news on the trial that Dr. Guha is conducting is very interesting. Please keep us posted if you learn anything else.
