Malignant brain tumors are one of the most lethal forms of cancer. Approximately 70,000 new cases of primary brain tumors were diagnosed in 2013. In 2010, researchers estimated that more than 689,000 people in the United States were living with a primary brain tumor. These statistics double if metastatic brain tumors (tumors which spread from other cancerous lesions) are also accounted for.
Each year, approximately 4,300 patients under the age of 20 will be diagnosed with primary brain tumors. Seventy-five percent of those patients will be under the age of 15. Brain tumors are the second most common and second deadliest of all cancers in children under the age of 15.
