Hi Ric,
I've read your posts. You say you don't know what your gut is telling you, but I think you do. From reading your posts, it seems to me that the headache fear is much greater to you than the low risk of radiation-caused malignancy or any of the other side effects of surgery or radiation. As you've read I'm sure, the risk of a malignant brain tumor is very low and a lot of the info out about it is to scare people away from radiation. Yes there are always risks with any procedure.
You have a fairly small tumor; to me, you can afford to wait and watch a while even with your family history. I agree with Bruce; I think radiation would be a very good choice if you decide you want to do something now (or even later). Some times you can overwhelm yourself with too much information and end up being more confused. Just sit quietly with your feelings, and check inside for what you really want to do and what feels right to you. If it isn't clear to you yet, then don't rush. You have some time to get a strong "yes" inside. And your choice may have nothing to do with statistics in the end.
I'm in the middle of a 28-day FSR treatment plan right now for a tumor larger than yours. I also overwhelmed myself with lots of research, reading all the posts here, and meeting with 6 docs of different specialties. I feel good about my choice, I feel good right now while I'm going through treatment, and I know that whatever happens, I made the choice that was right for me. I know you will do the same thing. Just give yourself time to digest all you've heard and read-- and be with your feelings. You'll get some certainty at the right time.
I'll be praying for you,
Beverly
