What’s the role of surgery in treating a brain tumor?

If the tumor can be removed or resected (removed) without affecting normal brain function, surgery is usually the first line of treatment. For example, Grade I meningiomas don’t typically invade the brain, so they are much more likely to be resected successfully. On the other hand, high grade gliomas mix with (or infiltrate (mix with)) normal brain cells, so these gliomas are less likely to be resectable. If a tumor is located deep in the brain and surrounds critical structures like blood vessels it is more challenging to remove and requires a multidisciplinary team with specialists in multiple neuroscience disciplines to treat it, like the team we have here at Premier Health.
