Let me see if I can find an oncologist expert that can answer your two questions:
1. My son's tumor was upgraded from Astrocytoma grade 2 or 3 to GBM. Can be done without another biopsy or can it be done based solely on increasing seizure symptoms?
2. When seizures occur after the resections, is it still considered epilepsy?
I will post the expert's response as soon as we we hear back!
