Hi Jo Ann and welcome to this forum of caring, supportive new AN friends .....
I can well remember the terror I felt when first hearing the words "Looks like you have a tumor." My brain froze and I could not even think what questions to ask, let alone anything the doctor was telling me. I had gone by myself to the appointment ..... sure he was going to say all the tests are normal. Right up front, my doctor said House Ear Clinic in Los Angeles is the best place to go for treatment but it is a long ways from here. End of first story, I went to Duke University in North Carolina for surgical removal (which is a 6 hour drive from where I live).
There are many excellent physicians around the country. The most important thing to know is how many ANs they treat each year (since they are so rare). This is one time when you want someone with vast experience in the treatment of acoustic neuromas, specifically, not just brain tumors.
If you have not already done so, you should send for the free informational booklets from the ANA (see
http://anausa.org/index.php/contact-us/free-ana-information-packet ). You can also look at the medical resources on the home page (
http://anausa.org/index.php/medical-resources ) for additional information on selecting a physician. Keep in mind that not all qualified physicians are listed on the ANA list.
There are also a number of highly respected medical facilities around the country who will do free consultations for additional opinions, if you send your MRI and most recent audiogram to them ..... this includes both surgeons and radiotherapy physicians.
As Jim said, at 1.2 cm, you should have all three options (wait and watch, surgical removal, or radiosurgery), unless your symptoms are debilitating or your AN is already pressing on the brainstem or cochlea.
Tell us a little bit more about your situation, symptom-wise.
Many thoughts and prayers as you walk through this research/information finding and treatment decision-making phase of this whole thing (in many ways the most troubling part).
