Hi Ron and Sam,
Well, for me.... I had my CK the first week of April of 2006. I had a 6 month MRI and at that time, there was no further growth of the AN (mine was growing at a good clip). Due to other issues, I had another head MRI at 8 months... at the 8 month MRI (I took a really good look at the films prior to meeting with my radio-oncologist) and he did confirm.... the beginning stages of "tumor death" was commencing. As you may know, it may take 1-1/2 to 2 yrs for the tumor to die, but the beginning stages were seen on my films at 8 months. (in looking at the films, you could see the center area of the AN almost "shadowed" - darker, than the outter rim. The Radiologist report confirmed a "rim-enhanced" growth with a darkened center).
It was my early holiday present in December.
Wishing you a VERY quiick tumor death as well!
Phyl
