Meningioma: Statistics

Approved by the Cancer.Net Editorial Board, 04/2014

ON THIS PAGE: You will find information about how many people are diagnosed with meningioma each year and some general survival information. Remember, survival rates depend on several factors. To see other pages, use the menu on the side of your screen.

In the United States, meningioma accounts for more than 36% of primary brain tumors, which are tumors that start in the brain, and occurs in approximately seven to eight of every 100,000 people. Meningioma is rare in children.

As discussed in the Overview, about 80% of meningiomas are noncancerous. The remaining 20% are likely to come back after treatment, and 1% to 2% of these become cancerous.

The ten-year survival rate is the percentage of people who survive at least ten years after the meningioma found. The ten-survival rate for malignant meningioma is around 57%. Survival rates for meningioma depend on several factors, including the age of the patient and whether the tumor is cancerous.

Survival statistics should be interpreted with caution. Estimates are based on data from thousands of people with this type of tumor in the United States each year, so the actual risk for a particular individual may be different. It is not possible to tell a person how long he or she will live with meningioma. Because survival statistics are often measured in ten-year intervals, they may not represent advances made in the treatment or diagnosis of this tumor. Learn more about understanding statistics.
