BRAIN AND NERVOUS SYSTEM TUMORS
Brain and central nervous system tumors are the second most common cancers in children, making up about 21% of childhood cancers. There are many types of brain tumors, and the treatment and outlook for each is different. Most brain tumors in children start in the lower parts of the brain, such as the cerebellum or brain stem. They can cause headaches, nausea, vomiting, blurred or double vision, dizziness, and trouble walking or handling objects. Adults are more likely to develop tumors in upper parts of the brain. Spinal cord tumors are less common than brain tumors in both children and adults.
