The most common brain tumor in children is called a low-grade glioma. It is a type of tumor that originates in the glial cells of the brain. Glial cells are the supportive cells that help the neurons in the brain communicate. Low-grade gliomas occur most frequently in the cerebellum and brain stem.
Low-grade gliomas are usually slow-growing tumors that have well-defined borders. They are classified as low grade because they do not spread as quickly or aggressively as other types of brain tumors. While these tumors usually do not spread to other parts of the body, they can still cause damage to the brain and surrounding tissue.
Symptoms of a low-grade glioma depend on the tumor’s location and size, but can include headaches, nausea, vomiting, seizures, and weakness. Treatment for these tumors typically includes surgery, radiation therapy, and chemotherapy. In some cases, the tumor can be surgically removed. If the tumor cannot be removed, radiation therapy and/or chemotherapy may be used to shrink the tumor and reduce symptoms.
Low-grade gliomas are the most common brain tumor in children, but they are still rare, affecting only about 3 in 100,000 children. It is important that any suspicious symptoms are discussed with a doctor, so that proper diagnosis and treatment can be pursued.
