What is (are) Childhood Brain Stem Glioma ?
Key Points 
                    - Childhood brain stem glioma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain stem.    - Brain tumors may be benign (not cancer) or malignant (cancer).     - There are two types of brain stem gliomas in children.    - The cause of most childhood brain tumors is unknown.     - The signs and symptoms of brain stem glioma are not the same in every child.    - Tests that examine the brain are used to detect (find) childhood brain stem glioma.    -  A biopsy may be done to diagnose certain types of brain stem glioma.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                 
                
                    Childhood brain stem glioma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain stem.
                    Gliomas are tumors formed from glial cells. Glial cells in the brain hold nerve cells in place, bring food and oxygen to them, and help protect them from disease, such as infection.     The brain stem is the part of the brain connected to the spinal cord. It is in the lowest part of the brain, just above the back of the neck. The brain stem is the part of the brain that controls breathing, heart rate, and the nerves and muscles used in seeing, hearing, walking, talking, and eating. Most childhood brain stem gliomas are pontine gliomas, which form in a part of the brain stem called the pons.      Brain tumors are the third most common type of cancer in children.   This summary refers to the treatment of primary brain tumors (tumors that begin in the brain). Treatment for metastatic brain tumors, which are tumors formed by cancer cells that begin in other parts of the body and spread to the brain, is not discussed in this summary.    Brain tumors can occur in both children and adults; however, treatment for children may be different than treatment for adults.

                    Brain tumors may be benign (not cancer) or malignant (cancer).
                    Benign brain tumors grow and press on nearby areas of the brain. They rarely spread into other tissues. Malignant brain tumors are likely to grow quickly and spread into other brain tissue. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Both benign and malignant brain tumors can cause signs and symptoms and need treatment.
                
                
                    There are two types of brain stem gliomas in children.
                    Childhood brain stem glioma is either a diffuse intrinsic pontine glioma (DIPG) or a focal glioma.         - DIPG is a high-grade tumor that is fast-growing and spreads all through the brain stem. It is hard to treat and has a poor prognosis (chance of recovery). Children younger than 3 years diagnosed with DIPG may have a better prognosis than children who are 3 years and older.    - A focal glioma is slow-growing and is in one area of the brain stem. It is easier to treat than DIPG and has a better prognosis. + CancerGov + Childhood Brain Stem Glioma
