Hi Chris;
Yes, the 1st AN was found when I was 27 in 1977. They did not have MRI then so I had to have a mylegram ( spinal tap, with contrast and x-ray )
The second tumors... There were 2 on the right side vestibular nerve which were seen on MRI 17 years later. Of course no one knows exactly when the tumors start as generally, they grow slowly in Gardner pts.
The 10 spinal tumors were all discovered in one MRI. Their number or size did not change in subsequent, yearly MRIs from 2000 on. They are about 1 - 2 mms, all located in the lower spine ( cauda equina )
As a music producer, I would really try to take Avastin though I think it's still in study for AN, I believe, AND, expensive! Seems Avastin producer, Phizer's Genetech Corp. has taken a recent hit with Avastin as it's been found not useful for breast cancer? I'm unsure if one can take the drug indefinitely and believe it only helps about 50% of those with NF-2.
Guess I have read a couple stories where people in their 60s have had their NF-2 ANs grow rapidly after being stable. I think, however, most in mid life and elderly enjoy relative tumor stability. I'm thinking studies lean toward a somewhat lowered life span average for NF-2 of even the Gardner variety. Say, perhaps 64 years? Sorry, I don't have ready link.
Each day w/o aggressive growth is a blessing! I hope you remain Mosaic, Chris.
