Empath,
Welcome to the forum! Nobody likes having to be here, but we all love the fact we are. Your first reaction is perfectly normal. I was convinced I was gonna die when first diagnosed. First, unless this thing grows large and left untreated, it's not going to kill you. That's a good thing. The hearing loss and tinnitus due to the AN (unfortunately) is a fact of life now (although, it could change the tinnitus a little bit).
You say "small", but do you know what size it is currently? Depending on the size (and other factors), you have several different options. Also based on size (and other options), you have plenty of time to decide what method of treatment. Mine was 30mm, so time was not something I had a lot of. Others are 3, 4 or 12 mm, and time was on their side to determine what method of treatment. They typically grow 1-2 mm per year on average (others faster, others slower).
Depending on size and location, you can choose CK, GK radiation or if you are one "that wants it gone now!" then surgery is the way to go and you can have translab, retro, or middle fossa. Your treating doctor will give you an opinion as to the best approach based on size and location.
I encourage you to search through the site. Find out all you can about treatment methods, "issues" that people are left dealing with, how long they've dealt with them, etc.. Ask questions. None of us are doctors, but we've all been where you are and can give advice or lend an understanding ear (no pun intended).
Probably one of the most important things is that you find a doctor who's experienced (VERY experienced) in treating ANs. You don't want a regular GP monkeying around with this. If your current doctor isn't very experienced in treating ANs, then find one who is. Your best chance for treatment outcome is with one who understands the AN treatment options. (FYI, you'll find that even doctors will "push" what they are comfortable with.. i.e. one who does a lot of GK will probably tell you that GK is the best option; while you talk to someone comfortable with the retrosigmoid surgery will probably tell you that retrosigmoid surgery is best.. they'll usually go with what they are comfortable doing...not always, but more often than not).
Again, welcome to the forum. You've found THE place for friendship, support, and most of all real-life experience-based information from people who have been there.
You can begin by telling us all more about what you know about the tumor. Size. Location (if known). How were you diagnosed?
Regards,
Brian
