Brain Tumors: An Overview of Symptoms, Diagnosis, and Treatment

Introduction

An abnormal growth of cells in the brain is called a brain tumor. Brain tumors may be malignant (cancerous) or benign (non-cancerous).

Suspicions of a brain tumor may first arise from abnormal behavior or other symptoms. Symptoms are typically investigated with a series of tests aimed at making a diagnosis. If a brain tumor is the diagnosis, further information about the cancer cells is necessary to determine the best possible approach to treatment. There are many types of brain tumors that differ based on which type of cells make up the tumor. Also, determining the extent of the cancer helps the doctor to understand the likelihood that the tumor will spread into other brain tissues, a characteristic which may also be referred to as the aggressiveness of the cancer.
