Mark .....
Good to read that your AN is basically the same, or only slightly larger. That is good news. This means you do not need to be in a rush to make a decision for treatment ..... unless your symptoms (hearing loss, for example) are getting worse.
His view was that given my age etc I was likely not be able to 'watch and wait' for ever, and that although my AN is fairly small, the more it grows the more difficult it is likely to be to remove surgically.
I am not sure what your neurosurgeon means by more difficult to remove surgically unless it started growing very close to the brain stem, which could make a difference in how long you wait to have treatment.
I do not know anything about radiation treatment possibilities in the UK, but here in the United States the protocol for radiation of ANs is rapidly changing. New research in the way of longer studies now is finding that the precise locating and less radiation of the newer GK and CK treatments is yielding far fewer side effects than previously. There seems to be a difference of opinion on whether radiation makes possible surgery later more difficult.
For some of us the issue was one of whether or not we wanted the tumor removed or the growth of the tumor stopped while staying in one's head.
I was a little puzzled about the BAHA implant being done at the time of surgery. Your first post indicated high frequency hearing loss. Has your hearing decreased more in the past six months?
Depending upon the surgical approach taken, sometimes hearing can be saved. I do not think hearing can ever be improved from what you currently have and most times you will lose at least some more but many of us have retained at least some of our hearing. Is your neurosurgeon recommending a translab approach? If so, that would result in total hearing loss and the reason he is saying a BAHA could be inserted at the time.
In any event, you have time to do your research and at some point in time you will know which decision is right for you. No one should try to sway you to their particular choice for treatment.
Best wishes and let us know how things are going.
