Brain tumors are the conditions in which the growth of abnormal cells in the brain, caused by uncontrolled cell division. Generally, brain tumors found in the brain itself, in the nerve tissue of the head, brain membrane, shell, or spread from cancers primarily located on the location of other organs in the body.Diklasfisikasikan brain tumors into two types, primary brain tumors and secondary brain tumors. Primary brain tumors are brain tumors that originated from other parts of the body and spread to the brain. Primary brain tumors can be divided into two types based on its nature, malignant (malignant) and benign (benign).
Malignant tumors (malignant) tumor that is contained cancer cells, which divide and grow quickly and invade healthy tissue around it. Unlike benign tumors (benign) that can live with normal cells, but sometimes can cause neurological disorders that cause seizures, changes in the nature, memory loss, and disrupt vital brain functions. While secondary brain tumors, malignant and is always fatal.
Ignoring age, brain tumors can arise at any time, but brain tumors that arise in infants and children must have different properties from the brain tumor that affects adults. Both in terms of cell types and the effect of treatment. Here are some types of brain tumors that are often found in children, among others, astrocytomas, brainstem gliomas, ependymomas, and medulloblastomas.
The cause of brain tumors is still unknown, but there are several factors that play a role in the formation of brain tumors, such as radiation to the brain and hereditary disease that may increase the risk of developing brain tumors such as neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome. Mobile phone use, brain injury, the effects of a specific chemical or magnetic fields cited as factors external causes brain tumors, but more research is still needed to find a relationship between these risk factors.
Personality changes are often the first symptom of a brain tumor. Before the discovery of the tumor, within a few weeks or months will look lethargic, irritable, hyperactive, forgetful or bad academic value. In general, people have difficulty concentrating because of the presence of a tumor in his brain.
Neurological tests, magnetic resonance imaging (MRI), and a CT scan is the preferred method to check the existence of a brain tumor. If after the diagnosis of a tumor in the brain, there are several methods of handling or treatment depends on the size and type of tumor and overall child health.
Treatment may include surgery, radiation and brainste glioma with chemotheraphy to shrink tumor size and prolong lifespan. In addition to treatment methods, can also use corticosteroid medications, such as dexamethasone (to reduce swelling of the brain), diuretics (urea or mannitol) to reduce swelling and pressure, anticonvulsants (phenytoin or leveiracetam) to reduce cramping and other treatments to manage pain .
Some tumors can be cleaned thoroughly, but not with tumor on the network and can only be reduced because it can not be retrieved or thoroughly cleaned. Brain tumors are dangerous and fatal disease. Therefore, parents need to recognize the symptoms of a brain tumor early on so it can be addressed properly and quickly.
