Hello again!
I’d say we have more people with a @BrainCerebellum AVM getting treatment these days than we had. It’s definitely one where it can be best left untouched in many cases but I feel there are more people mentioning here that they are having treatment.
Cyber knife is also less common but I think that is to do with the availability of the equipment to do the work: I assume it is a very expensive piece of kit. So far as I know, it does very much the same work as gamma knife radiotherapy. We do have a topic about different types of radiotherapy in our AVM 101 category.
Overall, I think you’ll find plenty of friends worrying about the same things as you who have gone through gamma knife.
I hope you have a good day of it and I hope it improves your Christmas rather than spoil it in any way.
Very best wishes,
Richard
