Meningioma's are tumors in the meninges, the membrane that surrounds the brain and spinal cord. Most meningioma's are benign though they can rarely be cancerous.
Meningiomas
They originate in the membranes that enclose the brain and spinal cord (meninges)
They represent more than 20% of all primary brain tumors
These tumors are usually benign and most often occur in women aged 30-50 years old
Meningioma is a tumor that is found on the meninges. The meninges are the covering that can be found surrounding the spinal cord and brain. Most meningiomas that are found are benign and rarely cancerous.

Benign tumors, such as fibroadenomas in the breast or meningiomas in the brain, tend to stay localized and have a capsule that separates them from surrounding tissues. This encapsulation distinguishes them from malignant tumors, which are more likely to invade nearby tissues and spread to other parts of the body.
The thickening of the dura mater, the tough outer layer of the meninges surrounding the brain and spinal cord, can be caused by various factors. This can include conditions such as meningiomas (tumors arising from the meninges), inflammatory conditions like meningitis or sarcoidosis, trauma, or accumulation of cerebrospinal fluid due to conditions like hydrocephalus. Diagnosis and management would depend on identifying the underlying cause.
Whether a meningioma will require surgery depends on various factors, including its size, location, and symptoms. Many meningiomas are slow-growing and may be monitored with regular imaging if they are asymptomatic. However, if the tumor causes significant symptoms or shows signs of growth, surgical intervention may become necessary. Ultimately, the decision is made based on individual circumstances and in consultation with a medical professional.
Any brain tumor is bad, however, it is one of the better ones to have. Meningiomas are slow growing tumors of the outside lining of the brain. They usually can be removed and completely cured. Occasionally they are in a location that cannot be completely removed which would be a problem.
A large mass on the frontal lobe with edema and a shift could indicate a brain tumor or other space-occupying lesion. The mass is causing swelling (edema) and displacement of surrounding structures (shift), which can lead to neurological symptoms and require urgent medical attention. Further imaging and medical evaluation will be needed to determine the specific cause and plan appropriate treatment.
Meningiomas are typically benign brain tumors. They are located in the dura or lining of the brain. On rare occasion they go into the bone. Benign does not mean without deficits or problems however. They are determined on a grading system class 1, 2 or 3...benign, atypical or malignant. Atypical meningioma has a higher chance of recurrence and malignant which are much rarer are cancerous. In answer to you question, most people have them removed and go on to live normal lives. I have had 2 removed...2 surgeries. I am very lucky. I do know of others who have had their lives changed totally and a few who have not made it. This is totally extreme but can happen. You must keep in mind that with any surgery fatality can be an issue.
