A brain tumor is the result of uncontrolled growth of cells in the brain. Primary tumors start and grow in the brain, while secondary tumors form because a tumor located in another part of the body has metastasized.
Neurological Exams are Used for Diagnosis
Neurological exams include checking vision, hearing, balance, coordination and reflexes. These tests provide clues about the area of the brain impacted by a tumor.
Various Factors Impact Classification
Tumor classification is dictated by various factors, including the exact site of a tumor, the type of tissue involved and whether the tumor is cancerous.
