Q. Anybody familiar with schwannoma?

A. Well, not personally, but generallly it's a tumor of the envelopes of the nerves. You can start with reading about it here (http://en.wikipedia.org/wiki/Schwannoma) and about the more commomn type, the one that affects the nerves of hearing and the face, you can read here (http://en.wikipedia.org/wiki/Acoustic_neuroma).
