question: I have type 2 neurofibromatosis, I have had surgery to remove most of the tumors, now I have 3 large fibromas left in my jaw/cheek.  I thought cyberknife would be an effective treatment but my Dr said the tumors were too close to the surface, and they cant be removed surgically because the risk of facial paralysis is very high.  my question is, would brachytherapy be a good option for my case?
