Gliomas are a common type of brain tumor that originates in the glial cells, which support the nerve cells of the spinal cord and brain. Gliomas are the most common type of brain cancer found in children and young people, and they can be classified based on the type of glial cell involved, their growth potential, and their level of aggressiveness. The exact cause of gliomas is unknown, but there is a hereditary component that can make some children more susceptible to developing a brain tumor. Symptoms of glioma can include headaches, seizures, vision problems, slurred speech, and changes in behavior. Treatment options for glioma vary depending on the grade of the tumor and its location. Some low-grade tumors may be treated with surgery alone, while others may require numerous surgeries or treatments such as chemotherapy, radiotherapy, and proton beam radiotherapy.
