Brain tumor is one of the most common reasons of mortality in children and in adults worldwide[1]. In India, tumors of the Central Nervous System (CNS) constitute approximately 35% of all childhood malignancies and are the second most common childhood tumor after leukemia. It is the leading cause of cancer-related deaths in children [2]. Braintumor is a group of abnormal cells formed by uncontrolled cell division, which grows inside the brain or around the brain [1].
