Julie - Even though I do not have an acoustic neuroma, I have been part of this board for the past 3-1/2 years. I have a schwannoma of the 9th cranial nerve (also told it was rare) which would affect my swallowing , gag reflex, and give me a hoarse voice. I have been a "wait and watch" patient with the tumor starting at 9 mm and recently measured at 12 mm, but with no pressure on the brainstem. The neuroradiologist told me he thought the first reading at 9 mm was "under-read" and that a few mm's over 3-1/2 years is not significant. It could be due to different technicians, different machines, etc. I have been watching it and any symptoms (none that I can detect) very closely and would opt for radiation if it grew to affect me. I was told it was in a difficult spot to get to surgically. The other factor is recent surgery for breast cancer (no relation to what's going on in my head) and having my husband have surgery on another type of benign brain tumor called a meningioma. So, my plate has been "full", but we take one day at a time and, as both of our MRI's recently were favorable, have been enjoying this break from medical issues. Good luck to you and keep us posted.
