Brain tumors are tumors that occur most often in children. There are about 1,500 children in the United States are diagnosed with a brain tumor each year, brain tumors are abnormal cells growing in the brain caused by uncontrolled cell division. Normally, brain tumors can be found in the brain, the nervous tissue in the head, in the mountains in the brain, skin, or spread from cancers primarily located in the position of other organisms.
Brain tumors can be classified into two types, namely primary and secondary brain tumor brain tumor. Primary brain tumors are tumors that develop in the brain, whereas secondary brain tumors are brain tumors that originated elsewhere in the body and spread to the brain. Secondary malignant brain tumors are uniformly fatal. Primary brain tumors can be divided into two types according to their malignant nature (malignant) and benign (benign). Malignant tumors are tumors that contain cancer cells that divide and grow rapidly and invade the surrounding healthy tissue. In the end, will destroy malignant tumors or destroy normal cells and interfere with the function of these cells. Malignant tumors can kill patients. On the other hand, benign tumors are more benign than malignant. These benign tumors can live with normal cells.
However, sometimes as a tumor can cause neurological disorders or nervous, such as seizures, memory loss and changes in the nature, and can also interfere with the important brain functions. As a result, some benign brain tumors can also be harmful to the patient's life.
Brain tumors can occur at any age. The resulting brain tumors in children has different characteristics of brain tumors in adults, whether it be cell type and the treatment effect. The majority of brain tumors rarely appear in the first child, but some tumors usually appear at a certain age. Some brain tumors are often found in children are astrocytomas, brain stem glioma, ependymomas and medulloblastomas.
Astrocytomas are usually non-cancerous or benign, and contains a cyst that develops slowly. These brain tumors usually develop in children from 5 to 8 years. Brain stem gliomas are brain tumors that appear only in children. The average age at which this tumor develops at the age of 6 years. These tumors can grow very large before causing symptoms. Ependymomas account for 8-10% of brain tumors in children. This type of tumor in very small channels (ventricular) in the brain and the brain stops the flow of cerebrospinal fluid (cerebrospinal fluid, CSF). Brain tumors are most common in children is medulloblastoma. Brain tumors are more common in boys than girls, usually at the age of 5 years seems medullloblastoma usually before the age of 10 years.
So far, the cause of brain tumors is unknown, but there are certain risk factors that may play a role in the formation of brain tumors, including the impact of radiation on the brain and hereditary diseases that can increase the risk of developing brain tumors such as neurofibromatosis, von Hippel-Lindau syndrome, Li-Fraumeni syndrome and Turcotte In general, tumors of the brain contain abnormalities in the genes associated with regulation cell cycle, resulting in cell growth that can not be controlled. These anomalies are caused by changes in the gene or the preparation of chromosomes that can alter gene function. Children who have received radiation therapy to the head in the treatment of other diseases were also at increased risk for the formation of new brain tumors. , factors external causes, such as mobile phone use, the incidence of brain damage, or exposure to certain chemicals or the magnetic field is still in research phase.
So far have not found a strong correlation between these risk factors for brain tumors, but further research is urgently needed.
The intensity of the symptoms of brain tumors in each individual according to the tumor specific type of tumor and tumor size. Nausea, numbness in the limbs, and convulsions are symptoms of primary brain tumors. In addition, the headaches experienced by patients with brain tumors very strong and usually occurs in the morning. Patients usually have a hard time to overcome the headaches with medication is often a puzzle. Seizures occur because of changes in the flow of fluid in the brain. Patients with brain tumors often have medical problems such as memory loss, difficulty speaking, confusion, and others. Patients generally make it difficult to concentrate because of the presence of tumors in the brain. In addition, even changes in personality or personality can occur in patients with brain tumors.
Brain tumors are diagnosed using advanced computer technology for describing the brain in different ways. There are different choices of methods to check for brain tumors, among other neurological tests (neurological examination), magnetic resonance imaging (MRI) and computed tomography.
In the neurological tests, doctors will check vision, hearing, mental alertness, muscle strength, coordination and reflexes. The doctor will also check your eyes to look for swelling caused by a tumor pressing against a nerve that connects the eye to the brain. MRI is a big machine with a strong magnetic field and connected to a computer to create a detailed picture of areas inside the head. Sometimes a special dye inserted into a vein in the arm or hand to help show differences in brain tissue. The finished product can show abnormal areas, such as tumors. CT scan uses X-ray machine, which is also connected to a computer to make detailed images of the patient's head. In this test can also be a special dye is injected to abnormal area can be easily seen.
In some cases, doctors suggest that patients who take other tests such as angiogram, a test, spinal tap, and a biopsy (a biopsy). In an angiogram test, dye is injected into the bloodstream, which makes blood vessels visible on x-ray. If the tumors, the results of X-rays showed a tumor or blood vessels that feed the tumor. In the spinal tap test, the doctor taking a sample of cerebrospinal fluid (fluid that fills the space in the brain). Liquid, which has tested in the laboratory to check for cancer cells or other signs of abnormalities. Removing tissue to look for the presence of cancer cells is called a biopsy. Expert to examine the cells under a microscope to check for abnormal cells. The biopsy may be considered as a test for tumors, abnormal tissue that can become cancerous, and other conditions.
Testing biopsy is the only way to diagnose a brain tumor certainly helps determine the severity and treatment plan.
If after diagnosis was found in brain tumors, there are several methods of handling or treatment. Early treatment can improve the chances he has had good results. But the treatment depends on the size and type of tumor, and overall health of the child. The following are methods for treating certain types of tumors, including astrocytoma, the operation is brain stem glioma with radiation and chemotherapy to reduce tumor size and prolong life because of this operation type of tumor can not be done; ependymoma with a combination of surgery, radiotherapy and chemotherapy, and medulloblastoma with chemotherapy and radiotherapy, and also with the combination therapy of surgery.
Operating procedures are generally for almost all types of primary brain tumors (primary brain tumors). Some tumors can be cleaned thoroughly. However, tumors that are within the network would be reduced because it can not be retrieved or thoroughly cleaned. In cases where the tumor can be cleaned, the mode of operation, reduce pressure and relieve symptoms. The method of radiotherapy and chemotherapy can be used for a particular type of tumor. In addition to these methods, other treatments also used to treat primary brain tumors in children. Treatment may be the use of corticosteroid medications, such as dexamethasone to reduce brain swelling, diuretics (urea or mannitol) to reduce swelling and pressure, anticonvulsants (phenytoin or levetiracetam) to reduce seizures and medication-medication for pain.
Brain tumors in children is a very dangerous disease and can be fatal. According to experts NCBI three of four children, survives after being diagnosed with brain tumors. It is therefore important for parents to recognize symptoms of brain tumors from the beginning that can be treated appropriately, so that the side effects or complications of the disease, such as nerve damage, may be avoided.
