I was diagnosed with a small AN when I was 54. I was having severe vertigo attacks, the full spin variety. They were severe, long lasting and debilitating. They became more frequent, totally unannounced, and unpredictable. I didn't give Watch and Wait any thought, my tumor needed to be addressed. I chose surgery because I wanted some finality to the little guy, but I was a good candidate for radiation. I was fortunate, my hearing was preserved ( albeit somewhat muffled ), but I have no regrets, even though I still struggle with some balance issues, a feeling of a full head, and a ring, that can be quite nasty, depending on how I am feeling.
What I have learned from sharing on this site, is that no tumor is alike, and no recovery is alike, whether you chose radiation or surgery. My son works with a guy, whose daughter had a very large AN removed, she lost hearing on one side, but she recovered right away, and is back to living a normal life. Your age is working in your favor.
Before you make any decisions, learn as much as you can, because you want to make the very best decision that works for you. It has to be a decision that you will be comfortable with for the rest of your life. Be very satisfied and happy with the medical team you chose.
I wish you all the best, and continue to interact with the people on this site, they are full of great information and understanding.
