Thanks, skier, for your update. Whether it's positive or not, it is what it is, and we need to walk along side of you in your journey.
I have had just the opposite experience of yours. For me, two doctors have agreed on your #4 option: Consider RS surgery after the MRI shows growth. But I'm seeking another opinion because I am not real comfortable with waiting for months since my symptoms have become much worse while I'm waiting. But so far I have been given only one option. And you have been given too many options! At least you are in charge of your treatment choices (as difficult as that is). I feel like I am not in charge of my treatment, and so, in a way, I envy you, even though you may not feel adequate to be making the decision.
If you haven't done so already, I would encourage you to watch as many of the ANA videos as you have time for. They really are excellent, and the neurosurgeons and other specialists do a wonderful job of explaining the options. Then if you do not like Translab surgery, you could choose to go with radiosurgery or surgery with a different approach. Or you may be convinced that translab is the best option for you. If you choose to do radiosurgery, you can discover the pros and cons of doing Cyberknife or GammaKnife. You can watch the videos where they explain the Cochlear implant, and then decide if it is something you would like. You would also become familiar with some of the neurosurgeons on the other side of the country, and then you could decide whether it would be worth leaving New England and taking the risk of flying to Cincinnati or San Diego, Stanford or Nashville or Rochester or wherever. I know for me, watching the videos helped me to clarify some approaches I definitely did not want and changed my mind on other treatment options. But I really like the idea that you are in charge of your destiny and not someone else -- even though it is challenging for you. It is your life, and while the neurosurgeons can make their suggestions, you are the one who has to live with the results, not them. You do whatever you believe is best for you.
In terms of knowing who does a great job with Cyberknife in New England, you could do a search here in the discussion forums (in the search field above) and see what you might find. Or another option is to find an ANA group that meets in New England. With the pandemic, most groups are meeting over Zoom or Facebook. There may be those in the support group who had radiosurgery in New England and there may be those who considered having it done in New England but went elsewhere. It would be good to hear why some did (and who did their procedures) in your area and why some others did not have their treatments done in the region. They might have concerns about some practitioners there. I have found a support group to be very helpful to me.
Whatever you decide, I am rooting for you skier!
