Introduction
Although a Meningioma is a brain tumor, they do not arise from the tissues of the brain. They grow from the meninges – the three thin membranes covering your spinal cord and brain. 90% of these tumors are non-cancerous. However certain meningiomas can be malignant (cancerous) or atypical (neither benign nor malignant) in nature. Meningiomas generally grow inward and cause pressure on the brain and the spinal cord. They can also grow outward toward the skull, resulting in thickness.
Meningiomas are most common among women between 40-70 years of age but they can also occur in men. These tumors are rare in children. Meningiomas do not always require immediate treatment and they might not cause any significant symptoms or signs. Only a very small percentage of the meningioma tumors have been therapeutically challenging and aggressive. | |
