health

The prognosis of a brain tumor depends on whether the tumor is benign
or malignant, its location and grade, and the patient’s age and overall
health. Patients with Grade I tumors that can be entirely removed may
recover completely. The prognosis is poorer in very young children and
in elderly patients.
The five-year survival rate for patients with malignant primary
tumors is less than 10 percent even when these cancers are treated aggressively.
Most patients with metastatic brain cancer die as a result of the
primary cancer rather than from the metastases in the brain.
