I was diagnosed in May with AN. Repeat MRI oct and has grown but still small so on wait and watch. I been experiencing a lot more tinnitus and balance/dizziness in the last month. I feel like at times it is harder to walk. Like I am drunk or something! My hearing is still pretty good. My neurosurgeon said symptoms are totally unrelated to size of tumor you have. Could have a large AN with no symptoms or a small one with a lot of symptoms. When time comes, I will have surgery. I was informed that if you have radiation and surgery down the road is needed that it will be harder to do.
Good luck!
