What is cerebellar astrocytoma?
cerebellar astrocytoma is one of the most common types of malignant brain tumor in children. People over 10 years rarely develop cancer. Symptoms may vary depending on the size and accurate placement of cerebellar astrocytoma, but many patients experience headaches, nausea and a certain degree of problems with engine movement or mental confusion. When the tumor is discovered in the early stages, brain surgery is usually effective in complete removal of malignancy. Advanced or spread of cancer may require surgery, radiation and chemotherapy to reduce the chances of life -threatening complications. Doctors
do not yet understand the exact causes of cerebellar astrocytoma. Some limited research suggests that the condition may occur as a result of certain environmental factors during pregnancy. The expected mother, who is exposed to toxins or pollutants, may have a slightly increased risk of childbirth with brain astrocytoma. Also, the suspicious genetic mutace is a role in the development of the tumor and to theDyž specific genetic markers have not been identified.
Most cerebellar astrocytomas are slowly growing tumors that do not cause symptoms for several years. As the tumor grows, it can increase the pressure in the skull and lead to chronic headaches. Some children often become nauseous and vomiting often. Because the brain is the center of the engine control, the invasive tumor can cause a weakness or loss of feeling on the limb. Other problems may include problems with vision or speaking, poor judgment and memory, confusion and lethargy.
If a pediatrician suspects brain astrocytoma based on symptoms, he usually planned to consult with a neurologist. A neurologist can analyze the results from imaging scans to positively identify the tumor. Computer tomography, displaying magnetic resonance, ultrasound and X -rays can be useful in determining the size and placement of matter. After confirming the JS diagnosisOU discussed possibilities of treatment with the patient and family members.
Whenever possible, most neurologists prefer surgically brain astrocytomas. Modern surgical techniques allow experts to cut small tumors from the brain without causing damage to the surrounding tissue. This procedure has a very high level of success and most patients perform full recovery. In some cases, however, surgery is not possible because the tumor is too large or cancer has already begun to spread. Chemotherapy and radiation are options that help many patients recover from at least some of their symptoms if the operation itself is ineffective.
