- There are no premalignant (or in-situ) stages
- Even low-grade and benign tumors are dengerous (destruction/increase IcP)
- Gliomas rarely spread outside the CNS

Types
Based on the differentiation of the tumor cell:
- Astrocytomas

Most common adult glioma. As with other tumors, higher grade = worse prognosis.
Types and grades
- Low-grade (relatively benign)
- Pilocytic astrocytoma (WHO grade I)
- Most often comes with a cystic growth
- The cyst is more concerning than
