Hi Dave,
AN's grow one cell at a time. One day, for whatever reason, (and I don't think playing in a symphony has anything to do with it) the schwann cells on the coating of the balance nerve decides to go a little crazy. So, one by one, the cells grow into a non-maglinant tumor and proceeds to do it's thing, which varies from one person to the next. Depending on the person, the location of the AN and because it's a Tuesday (in other words, who know's why?) some people can grow a pretty good sized tumor before they notice symptoms. Other people will have big time problems and the AN is itty bitty. Technically you could call this a disease:
disease |diˈzēz|
noun
a disorder of structure or function in a human, animal, or plant, esp. one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury : bacterial meningitis is a rare disease | a possible cause of heart disease.I am not fond of saying that because to me, it sounds like it is passed from person to person, like a cold. You can just tell people it is a benign tumor growing on the balance nerve, but it also affects the hearing since the nerves are so close together. But, benign doesn't mean friendly. If a tumor can grow so large as to eventually press against your brain stem, then, no...it's not friendly. Next question will be the cell phone debate. No..not caused by cell phones or by stress or loud noises (but you can get tinnitus that way!) or by any by-product of the modern age, because that doesn't explain that people have gotten this for a long time, although it wasn't discovered until recent history, as in 100 years ago or so. NF2 has a genetic link. One sided AN's have not been proven to have that. You can google Chromosome 17 and read about some of the things associated with that.
Almost everybody who gets this questions why and how they got it. We all did. It's a natural question. Right after we say, "I have WHAT?", comes "And HOW and WHY did I get THAT?" I'm sure Michael J. Fox said that with his Parkinson's. So...the answer is that some of us humans will get a chronic illness/condition/disease ("persisting for a long time") some where along the line, and sometimes it's Vestibular Schwannoma/Acoustic Neuroma. And that's just the luck of the draw I guess. And our only compensation is that we live in 2010 and we have modern medicine to kill the darn thing.
After 4 years of living with my 'condition', I'm still gobsmacked that I have such a thing.
I'm also very grateful that I wasn't handed something far worse.
Feel free to read my blog on my AN, if you want to slog through it.
And you can always tell people that you are that one in a million who has this. Just think, you might be the ONLY person in Walla Walla with an AN!!
