A meningioma is a tumor that develops out of the protective membranes called meninges which surround the brain and spinal cord, states Mayfield Clinic for Brain and Spine. The majority of meningiomas are benign and grow slowly over time, but some may be cancerous. Symptoms often don't exist initially, and immediate treatment is not typically necessary due to the slow growth of the tumors. Treatment is usually concentrated on removing the tumor and relieving pressure from the brain.
Some meningiomas in the brain may not show symptoms at all, while others may create intercranial pressure that can lead to headache, vomiting or a loss in vision, according to Brain-Surgery.com. While the location of the tumor generally determines the symptoms, a common early symptom is seizures. As of 2015, researchers have not determined what causes meningiomas to grow or recur in certain individuals, although doctors agree that environmental and genetic factors are certainly key.Learn more about Conditions & Diseases
