Meningioma Brain Tumor Causes and Risk Factors of Meningioma Meningioma Symptoms Diagnosis of Meningiomas Meningioma Treatment A meningioma is a tumor that forms on membranes that cover the brain and spinal cord just inside the skull. Specifically, the tumor forms on the three layers of membranes that are called meninges. These tumors are often slow-growing. As many as 90% are benign (not cancerous). Most meningiomas occur in the brain. But they can also grow on parts of the spinal cord. Often, meningiomas cause no symptoms and require no immediate treatment. But the growth of benign meningiomas can cause serious problems. In some cases, such growth can be fatal. Meningiomas are the most common type of tumor that originates in the central nervous system. They occur more often in women than in men. Some meningiomas are classified as atypical. These are not considered either benign or malignant (cancerous). But they may become malignant. A small number of meningiomas are cancerous. They tend to grow quickly. They also can spread to other parts of the brain and beyond, often to the lungs. Causes and Risk Factors of Meningioma The causes of meningioma are not well understood. However, there are two known risk factors. Exposure to chemicals including bio chemicals of any kind. Exposure to radiation Neurofibromatosis type 2, a genetic disorder Previous injury may also be a risk factor, but a recent study failed to confirm this. Meningiomas have been found in places where skull fractures have occurred. Theyve also been found in places where the surrounding membrane has been scarred. Some research suggests a link between meningiomas and the hormone progesterone. Middle-aged women are more than twice as likely as men to develop a meningioma. Most meningiomas occur between the ages of 30 and 70. They are very rare in children. Meningioma Symptoms Because most meningiomas grow very slowly, symptoms often develop gradually, if they develop at all. The most common symptoms include: Headaches Seizures Blurred vision Weakness in arms or legs Numbness Speech problems Diagnosis of Meningiomas Meningiomas are rarely diagnosed before they begin to cause symptoms. If symptoms indicate the possibility of a tumor, a doctor may order a brain scan: an MRI and/or a CT scan. These will allow the doctor to locate the meningioma and determine its size. A biopsy may sometimes be performed. A neurosurgeon can remove a Meningioma depending on location. Please keep in mind MRI scans are required to diagnose and monitor the progress of Meningiomas. When getting MRI scans most neurologist prefer you have an MRI with contrast due to the fact that you get a much better reading if you are injected with the metal based contrast (gadolinium for example) which is used for highlighting vs getting an MRI without the metal based contrast. Please keep in mind the metal based contrast (gadolinium for example) can severely harm completely incapacitate and completely kill you if you are unable to adequately flush the metal based contrast immediately out of your system. The metal based contrast can shut your kidney system (nephrology system) completely down in addition to creating extreme havoc on your entire system by staying in your system and concreting your entire internal system. The metal based contrast (gadolinium for example) can complete concrete all of your internal and external organs your entire mixed connective tissue and entire vascular system. In addition to giving you extreme severe metal poisoning and cancer all resulting in extreme human suffering and very hard long suffering deaths. If you are adequately hydrated going into the MRI and do not have any kidney (nephrology system) problems in addition to any problems swallowing (dysphasia) you should not have any problem with they dye. However, there are some cases of others having immediate allergic reactions to the dye.
