Brain tumor facts medically edited by: Charles P. Davis, MD, PhD

  • The brain is the body organ composed of nerve cells and supportive tissues like glial cells and meninges – there are three major parts – they control your activity like breathing (brain stem), activity like moving muscles to walk (cerebellum) and your senses like sight and our memory, emotions, thinking and personality (cerebrum).
  • Primary brain tumors can be either malignant (contain cancer cells) or benign (do not contain cancer cells). A primary brain tumor is a tumor which begins in the brain tissue. If a cancerous tumor starts elsewhere in the body, it can spread cancercells, which grow in the brain. These type of tumors are called secondary or metastatic brain tumors.
  • Brain tumors can occur at any age.
  • Researchers and doctors do not know exact cause of brain tumors.
  • Risk factors include exposure to ionizing radiation and family history of brain tumors.
  • The signs symptoms of brain tumors depend on their size, type, and location. The most common signs symptoms include headaches; numbness or tingling in the arms or legs; seizures; memory problems; mood and personality changes; balance and walkingproblems; nausea and vomiting; or changes in speech, vision, or hearing.
  • Doctors group brain tumors are classified by grade (grade I, grade II, grade III, or grade IV -the most severe). The grade is determined by the way the cells look under a microscope. The higher the grade number, the more abnormal the cells appear, and the more aggressively the tumor usually behaves.
  • The most common types of primary brain tumors among adults are astrocytoma, meningiom (a tumor that arises from the membranes surrounding the brain and spinal cord) and oligodendroglioma.
  • The most common type of primary brain tumors in children are medulloblastoma, grade I or II astrocytoma, (or glioma) ependymoma, and brain stem glioma.
  • Studies have found risk factors for brain tumors to include ionizing radiation from high dose X-rays (for example, radiation therapy where the machine is aimed at the head), and family history.
  • Diagnosis of a brain tumor is done by a neurologic exam (by a neurologist or neurosurgeon), CT (computer tomography scan) and/or magnetic resonance imaging (MRI), and other tests like an angiogram, spinal tap and biopsy. Your diagnosis helps predict the treatment.
  • Neurologists base the treatment of brain tumors on the type, location, and size of the tumor, your health, and age. Treatment options may include surgery, radiation therapy, or chemotherapy (or a combination of treatments).
  • Supportive care is important before, during and after treatment to minimize symptoms and to improve your quality of life.
