Meningiomas make up about 20 percent of all brain tumors. A meningioma
is a type of tumor that develops in the meninges, the protective
membranes that cover the brain and the spinal cord. Most meningiomas are
non-aggressive, or benign, although up to 5 percent are aggressive, or
malignant. Benign meningiomas are slow-growing and do not invade
surrounding tissue or spread to other parts of the body, but they often
require surgery, because they compress adjacent brain tissue as they
grow.
Prognosis
Meningiomas fortunately carry an excellent prognosis--complete recovery usually occurs within a few months.
Initial symptoms
indicating
the growth of a frontal lobe brain tumor can be difficult to notice.
However, over time noticeable symptoms such as seizures and frequent
urination will begin to develop. It is important to stay vigilant if
someone you know displays these outward symptoms or others, such as
personality change and mood swings, as they may not be readily
acknowledged by the person
