about Brain Tumor:
- Brain tumors can occur at any age.
- 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 walking problems; 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. Some patients can qualify for clinical trials. Contact information is provided at the end
