Brain tumors in adults and children may lead to seizures and the onset of epilepsy. A brain tumor is an abnormal growth that can affect the brain, surrounding structures, and the body’s nervous system. Brain or nervous system tumors are usually separated into two categories: intra-axial tumors (tumors that grow within the brain) and extra-axial tumors (tumors that develop outside of the brain but are within close proximity to the brain tissues). Treatment plans for a brain tumor are determined by the proximity of the tumor to the brain, severity of the tumor and the speed at which it is growing. Surgery is often the first step in treating adults and children with brain tumors, and many patients may require radiation therapy and chemotherapy following surgery to eradicate any tumor cells that may have been left behind.
