|---|---|---|
| Low-grade (diffuse) astrocytoma | 73% | 46% |
| Anaplastic astrocytoma | 58% | 29% |
| Glioblastoma | 22% | 9% |

What is the prognosis for Grade 3 astrocytoma?
Grade 3 and grade 4 astrocytomas grow faster and are malignant, which means they’re cancerous. An anaplastic astrocytoma is a grade 3 astrocytoma. While they’re rare, they can be very serious if left untreated. Keep reading to learn more about anaplastic astrocytomas, including their symptoms and the survival rates of people who have them.
Is brain cancer the worst cancer?
Glioblastoma, the worst types of brain cancer, can take place in the brain or the spinal cord. They form from astrocytes supporting the nerve cells. This brain cancer type may occur to anyone, but it is mainly the older people who usually get it. Treating Glioblastoma is difficult.
Is brain cancer and a brain tumor the same thing?
Difference Between Brain Tumor and Brain Cancer. Tumor (tumour) is defined as new growth (neoplasm). Brain tumors are new growth of the brain tissue or the covering of the brain.
