Same as everyone, I think it really depends on your situation. I think if the tumor is small, and there is a good chance they can get it out without sacrificing your hearing and other nerves, surgery for me would be a better bet. Mine was considered medium sized though, and is in a tricky location, so they would have to sacrifice my hearing and I have a high chance of facial paralysis from surgery. For me, I am choosing radiation, but if it had been smaller and they had given me better odds of saving hearing and not having facial paralysis, I would have chosen surgery just to get it out and not have to worry about it anymore. However, surgery still does not guarantee you never have to worry about it. Nobody really knows what causes these things, although there is evidence that exposure to childhood radiation and people who have endocrine system issues (such as hypothyroidism like I have) have a much higher chance of developing these tumors. So even if you have surgery and remove it, another could grow in its place, albeit I don't think the likelihood is very high. So here are my pros and cons:
Radiation pros - outpatient procedure, so no recovery time, much lower chance of facial paralysis and other detrimental side effects, no chance of death, higher chance of hearing preservation for larger tumors.
Radiation cons - tumor is still there, no long term studies (this is only a factor is you are relatively young when diagnosed, they have up to 20 year data on this but maybe in 25 years all people who have radiation end up with brain cancer, nobody knows at this point), may still have to have surgery and radiation could complicate it, you have to live with not knowing what side effects you may end up with in the coming years.
Surgery pros - tumor is gone, no exposure to radiation with unknown long term effects, you know right away what your symptoms are going to be and can begin to adjust and compensate, if your tumor is causing serious balance issues surgery corrects this much faster while radiation can take several years or not at all.
Surgery cons - higher chance of facial paralysis and damage to other nerves in that area, lower chance of hearing preservations particularly with medium to large tumors, long recovery time, higher chance of death, it's brain surgery and they are going to be cutting a hole in your head.
