The American Cancer Society states that no apparent reason can be found for the development of brain tumors in children.
In addition, both the American Academy of Pediatrics and the National Cancer Institute recommend that children receive cancer diagnosis and treatment at one of the more than 200 medical centers in the U.S. The majority of brain tumors have abnormalities of genes involved in cell cycle control, causing uncontrolled cell growth. Patients with certain genetic conditions (neurofibromatosis, von Hippel-Lindau disease, Li-Fraumeni syndrome, and retinoblastoma) also have an increased risk for developing tumors of the central nervous system. Some chemicals may change the structure of a gene that protects the body from diseases and cancer. Children who have received radiation therapy to the head as part of prior treatment for other malignancies are also at an increased risk for new brain tumors. Increased intracranial pressure (ICP). ICP is caused by extra tissue or fluid in the brain. Examination of a brain tumor depends mostly on the types of cells in which the tumor begins and the tumor location.
As with any cancer, prognosis and long-term survival can vary greatly from individual to individual. Rehabilitation for lost motor skill and muscle strength may be required for an extended amount of time.
The loss of the myelin sheath insulating the nerves is the hallmark of some neurodegenerative autoimmune diseases, including multiple sclerosis. Nerve sheath tumors develop on cells that surround the nerves, most commonly affecting the arms and legs.
Nerve sheath tumors affect the peripheral nervous system, which is part of the central nervous system that connects the nerves in the body to the spinal cord and brain. There are a few different types of nerve sheath tumors, also known as peripheral nerve sheath tumors. Nerve sheath tumors affect the peripheral nervous system, which is the part of the central nervous system that connects the nerves in the rest of the body to the spinal cord and brain. Brain and spinal cord tumors are the third most common type of childhood cancer, after leukemia and lymphoma. The symptoms of childhood brain and spinal cord tumors are not the same as in adults or in every child.

MRI scan showing a intramedullary spinal cord tumour (arrowed) in the cervical spine, with the typical syrinx at the rostral and caudal aspects of the tumour. Most benign brain tumors have clear borders, meaning they do not invade surrounding tissue. Brain tumors that occur in infants and children are very different from adult brain tumors, both in terms of the type of cells and the responsiveness to treatment. The brain is an important organ that controls thought, memory, emotion, touch, motor skills, vision, respirations, temperature, hunger, and every process that regulates our body.
Located at the back of the head, the cerebellum's function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium. These abnormalities are caused by alterations directly in the genes, or by chromosome rearrangements that change the function of a gene.
There have also been some reports of children in the same family developing brain tumors who do not have any of these genetic syndromes.
Research has been investigating parents of children with brain tumors and their past exposure to certain chemicals, including pesticides and petroleum products. Pressure may increase because one or more of the ventricles that drain cerebrospinal fluid (CSF, the fluid that surrounds the brain and spinal cord) has been blocked, causing the fluid to be trapped in the brain. Some pituitary tumors may cause diabetes insipidus, with symptoms of abnormal electrolytes and changes in mental status. Your child's doctor tests reflexes, muscle strength, eye and mouth movement, coordination, and alertness.
A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body.
A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.

A diagnostic test that uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. A dye is used to visualize all the blood vessels in the brain with X-rays in order to detect certain types of tumors. Astrocytomas are glial cell tumors that are derived from connective tissue cells called astrocytes. Optic nerve gliomas are found in or around the nerves that send messages from the eyes to the brain. PNET can occur anywhere in the brain of a child, although the most common place is in the back of the brain near the cerebellum. Craniopharyngiomas are benign tumors that occur at the base of the brain near the nerves from the eyes to the brain, and the hormone centers.
Many different tumors can arise near the pineal gland, a gland which helps control sleep and wake cycles.
A VP shunt may be placed in the head to drain excess fluid from inside the brain to the abdomen. Speech therapists and physical and occupational therapists may be involved in some form of rehabilitation. They are composed of schwann cells, which are the cells that make up the protective nerve covering. Like schwannoma tumors, neurofibroma tumors are typically benign and made up of schwann cells.
They are usually found in individuals with the genetically inherited disease neurfibromatosis. In children, most common locations are in the lower part of the brain, such as cerebellum and brainstem. In certain cases, image-guidance systems (IGS) and intra-operative nerve monitoring are used to improve surgical results and outcome.
In such cases, surgery is not advised and the treatment is usually radiation therapy, followed by immunotherapy. The scan image on the right shows the spinal cord after the tumour has been surgically resected. These tumors can, however, cause symptoms similar to cancerous tumors because of their size and location in the brain. Malignant brain tumors very rarely spread to other areas of the body, but may recur after treatment.
Functions of the cerebrum include: initiation of movement, temperature sensation, touch, vision, hearing, judgment, reasoning, problem solving, emotions, and learning. Functions of this area include: movement of the eyes and mouth, relaying sensory messages (for example, hot, pain, or loud), hunger, respirations, consciousness, cardiac function, body temperature, involuntary muscle movements, sneezing, coughing, vomiting, and swallowing.
A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs, such as the brain. Most brain stem tumors cannot be surgically removed because of the remote location and delicate and complex function this area controls.
They are frequently found in persons who have neurofibromatosis, a condition a child is born with that makes him or her more likely to develop tumors in the brain. This tumor is rapidly growing and often blocks drainage of the CSF (cerebral spinal fluid, which bathes the brain and spinal cord), causing symptoms associated with increased ICP. The goal is to remove as much of the tumor as possible while maintaining neurological function. More research is needed to improve treatment, decrease side effects of the treatment for this disease, and develop a cure.
Malignant, or cancerous, peripheral nerve sheath tumors are called neurofibrosarcomas and are very rare. The schwann cells in these tumors, however, exhibit balletic inactivation of the neurofibromatosis gene, which basically means there is a slight genetic difference.
Tumors are treated with surgery, and if cancerous, they are treated with chemotherapy and sometimes radiation. Primary brain tumors start in the brain and generally do not spread outside the brain tissue.
Sometimes, brain tumors that are not cancer are called malignant because of their size and location, and the damage they can do to vital functions of the brain. Many symptoms are related to an increase in pressure in or around the brain, except in very young children (whose skull bones have not yet fused together), as there is no spare space in the skull for anything except the delicate tissues of the brain and its fluid.

These tumors may be particularly difficult to diagnose in adolescents because of the symptoms. Always consult your child's doctor for a diagnosis. There are several types of gliomas, categorized by where they are found, and the type of cells that originated the tumor. Brain stem gliomas occur almost exclusively in children; the group most often affected is the school-age child.
Persons usually experience loss of vision, as well as hormone problems, since these tumors are usually located at the base of the brain where hormonal control is located and arise (begin) from the optic nerve. The symptoms depend on their location in the brain, but typically the child experiences increased intracranial pressure. Medulloblastoma cells can spread (metastasize) to other areas of the central nervous system, especially around the spinal cord. Surgery for a biopsy may also be done to examine the types of cells the tumor is made of for a diagnosis. Side effects of radiation and chemotherapy, as well as second malignancies, can occur in survivors of brain tumors.
New methods are continually being discovered to improve treatment and to decrease side effects.
Another difference between schwannomas and neurofibromas is that the former are made of only schwann cells, whereas neurofibromas are formed with many different types of cells. They usually form in the deep soft tissue, most commonly occurring in the sciatic nerve, sacral plexus, and brachial plexus.
Even when all traces of nerve sheath tumors have been removed, there is always a chance of regrowth. Dogs usually develop these tumors late in life, whereas humans are diagnosed at the average age of 35. The child usually does not have increased intracranial pressure, but may have problems with double vision, movement of the face or one side of the body, or difficulty with walking and coordination. The tumor often blocks the flow of the CSF (cerebral spinal fluid, which bathes the brain and spinal cord), causing increased intracranial pressure. These tumors are fast growing and often malignant, with occasional spreading throughout the brain or spinal cord. A combination of surgery, radiation, and chemotherapy is usually needed to control these tumors.
Benign pineal gland cysts are also seen in this location, which makes the diagnosis difficult between what is malignant and what is benign. This is frequently done if the tumor is in an area with sensitive structures around it that may be injured during removal. The tumors are not harmless, however, and may cause nerve or bone damage as they grow and push against nerve fibers. Neurofibrosarcomas are typically diagnosed from a biopsy after the patient expresses symptoms of pain. Brain tumors, either malignant or benign, are tumors that originate in the cells of the brain. Ependymomas can be slow growing, compared to other brain tumors, but may recur after treatment is completed. Biopsy or removal of the tumor is frequently necessary to tell the different types of tumors apart. Astrocytomas are further classified for presenting signs, symptoms, treatment, and prognosis, based on the location of the tumor. Recurrence of ependymomas results in a more invasive tumor with more resistance to treatment. Although these tumors are benign, they are hard to remove due to the sensitive brain structures that surround them.
Persons with tumors in this region frequently experience headaches or symptoms of increased intracranial pressure. The most common location of these tumors is in the cerebellum where they are called cerebellar astrocytomas. These tumors usually cause symptoms of increased intracranial pressure, headache, and vomiting.
