What Are High Grade Gliomas?
High-grade gliomas are tumors of the glial cells. Glial cells are found in the brain and spinal cord. The tumors are called “high-grade” because they are fast-growing and spread quickly. This makes them hard to treat. The tumors occur in people of all ages, from infants to adults.
High-grade gliomas are rare and account for 8-12% of all childhood brain tumors. They occur equally in males and females.
High-grade gliomas are classified by their location and by how they appear when examined under a microscope. Classifying the tumor helps determine how the disease will progress and helps identify the best treatment for it. Although the outlook for high-grade gliomas is generally poor, some people can be cured.
