Thought i would give you another perspective, even though i am on W & W.... I was diagnosed in Oct. 2008, but have been losing my hearing for at least 12 years, maybe a little longer. So, i would have been about your age when i first noticed hearing loss. Since i can only guess that my hearing loss is due to the AN, i have been in this mode for awhile now - but could never explain it until now. (And i was somewhat relieved when i could give it a name!) BTW- i would not have gone to the doctor this year, had my sister not been diagnosed 6 months ago!
I immediately told my ENT i would W & W. But, after a second opinion, i decided it is important to learn all i can and do research, as well as visit a surgeon and radiologist in early 2009. This is just to be prepared, to know my options, if and when i need them.
My AN is slightly larger than yours, but i have no idea how long it has been that size, or how fast it might be growing. Since i can only go forward, i decided to try to be prepared.
I believe you have time to do research and learn all you can. With having little ones, if you decide on any treatment now or in the future, extra help and good planning could help make things go more smoothly after treatment.
I am so glad you asked this question! I am very thankful to all of those here on the forum - i have learned so much and continue to read as much as i can.
Take care.
