Hi Sher,
Welcome to our little club. Sorry you are becoming one of our newest members. First, remember to breath! It's hard when you are newly diagnosed with something you probably never heard of before. But breathing is a good thing! And keeping things in perspective is good also. That's also hard to do at the beginning when the news is so fresh and you are feeling overwhelmed and confused. This is a great site for you to learn about things, ask questions, find a friend, whatever it takes to help you get through this.
I also have a 2 cm AN. For various reasons, my treatment was done via Gamma Knife radiosurgery and now it's been over two years since my treatment and all is going well.
You can join the ANA here and they will send you literature to look at. That's a good first step. Your doctors will no doubt talk to you about a course of action. My advice would be for you to learn about Acoustic Neuroma and to learn the different methods of treatment. There is Watch and Wait, which probably won't be advised for you since your AN is in the medium catagory, microsurgery and radiosurgery. Since your tumor isn't in the large catagory, you might look into Gamma Knife or Cyber Knife or one of the other delivery systems for radiation which can effectively kill the tumor. Or you might decide that you'd rather have the surgery. You should talk to doctors that will give you a good idea of what each option would entail for you.
Or you can begin right here and ask a question. Any question. And somebody here will try to answer it for you. We've got some great people on here who would love to help you out any way that they can. Just know this isn't the end of the world and life goes on after AN's. Yes, it will be different in some way or another, but you'll be okay.
To help you get started, I'll ask a question or two of you! Where do you live? How old are you? What are your symptoms?
So glad you found this site. It's a big help and has been for so many people.
Take care, Sher.
