Welcome JK,
W&W is definitely the conservative approach and sounds like a viable option for you at this point.
These tumors are usually slow growing so there is time for research and testing and observation of symptoms.
Perhaps one of your doctors would agree to another MRI in about 6 months to see if there are any changes in size and or symptoms. If you are still doing well,, perhaps you would be comfortable waiting another 6 months to observe things,,,, many people follow this plan.
Only you can decide how you want to proceed. You don’t seem to have many symptoms which are affecting your quality of life and your hearing will deteriorate with time probably but treatment usually has consequences for hearing also.
Everyone handles these tumors differently depending on their situation and personalities,,, some want it out immediately and others are comfortable waiting. There is no wrong answer and that makes it difficult for many. Take your time to be sure you are comfortable with your decision and then move forward. Best wishes as you proceed,,,,
Jane
