Why do I still have seizures even thought I had surgery and had my brain tumor removed?

In brief: Not uncommon

Unfortunately, even with full tumor resection, only 80% of patients will have complete seizure disorder relief.
10% or so will note improved seizure frequency/intensity and the rest of the patients will have no improvement of their seizures despite surgery.

In brief: Scar focus

Tumors do not cause seizures.
They irritate regions of the brain that then cause seizures. After removal of a tumor the irritated brain areas may remain. In some cases further surgery is necessary to remove these areas. Eeg recordings during surgery can identify these areas for removal. Otherwise medications are appropriate to control the residual seizures.
