[…] several lines of treatment. [onlinelibrary.wiley.com]

Treatment Treatment options for meningioma include observation, surgical resection, radiotherapy, and systemic therapy, as well as a combination of these modalities. [mdedge.com]

Treatment The treatment consists of total surgical resection of tumor. Prognosis The major evolution is recurrence. The tumor grade provides the most useful predictor of recurrence. Benign meningiomas have a recurrence rate of about 7-20%. [atlasgeneticsoncology.org]

In adults, the age that a person is diagnosed with meningioma is one of the best ways to predict prognosis. In general, the younger the adult, the better the prognosis. Extent of tumor residual. Resection is surgery to remove a tumor. [cancer.net]

Prognosis The major evolution is recurrence. The tumor grade provides the most useful predictor of recurrence. Benign meningiomas have a recurrence rate of about 7-20%. [atlasgeneticsoncology.org]

Despite the morphological diversity, patient prognosis is often very good, which is mainly due to the benign, slow growing character of the tumors. [cco.amegroups.com]

Depending on the areas of the brain or spinal cord that are involved, radiation therapy may help shrink any remaining tumor and can also help prevent it from spreading to the tissues around it. [cedars-sinai.org]

Radiation can shrink the tumor or help prevent it from growing any larger. Radiation can also be used to kill cancer cells if the tumor is malignant. It may also be used on the parts of a tumor the surgeon was unable to remove. [webmd.com]

Prevention [ edit ] A number of measures have been attempted to prevent seizures in those at risk. [en.wikipedia.org]

We do not know how to prevent meningiomas. Recognizing the symptoms is important and early detection allows for more treatment options before the tumor gets too large. [mountsinai.org]
