Brain tumours are basically of two kinds – those that originate from the layers covering the brain (meninges) and those that originate from the brain cells. The former are called meningiomas. They are almost always non-cancerous and are easy to remove surgically. The tumours arising from the supportive tissues of the brain are called gliomas. They are more common in adults and are more dangerous, since they are usually malignant and can often not be completely removed.
The most commonly occurring tumours in adults are gliomas, while in children, tumours usually arise near the brain stem (medulloblastoma).
