Hi, Dave - and welcome!
Scheduling surgery is very situational and decided by the doctor's consideration of your need for the surgery and your input, of course. Waiting six months before even scheduling surgery indicates that your tumor must be very small and your symptoms are not increasing which usually indicates growth of the tumor - and a more relaxed approach. My AN was large (4.5 cm) when discovered and pressing hard on my brain stem. My neurosurgeon was very anxious to operate (the only option at that point) and I was in the OR 3 weeks after my initial consultation. It would have been sooner had not a false cancer scare arose during my pre-op testing that set back the surgery date by at least a week. However, that was me, with a big AN and symptoms growing more severe by the day. I suspect your situation is quite different but if surgery is your option of choice, I would want to move things along a bit.
Jim
