Mary,
I thought about radiation but I am a possible NF2 case since I had a schwannoma removed from my scalp 2 months before my first surgery. It means that I am at an increased risk of forming other schwannomas and meningiomas in general and from radiation especially. In addition, radiation in this particular case is not as reliable as in sporadic AN cases. In addition, the tumor is very attached to the brainstem, so they would have to radiate my brainstem. So, radiation for me is actually less reliable and more dangerous. I figured that if I have surgery now, I'll gain at least another 10 years should the tumor recurr again. There is a possibility the surgeon will leave a piece on my facial nerve to avoid complete damage to it because it is already thinned out from my first tumor and a surgery even though it is functioning perfectly, can't complain. Then I can potentially risk radiation if the new tumor is small and spherical or maybe there will be something else available. If I have radiation now and the tumor swells, it is big enough to cause an irreparable damage; if the treatment fails, the microsurgery is going to be even more difficult and by then I will need a miracle to preserve any nerve function. That's my logic. I know every case is different. I feel that by choosing microsurgery again, I have a greater chance of tumor removal as well as nerve preservation. I just hope it happens. Take care.
