Risk factors for a meningioma include:
Radiation treatment: Radiation therapy that involves radiation to the head may increase the risk of a meningioma.
Female hormones: Meningiomas are more common in women, leading doctors to believe that female hormones may play a role. Some studies have also suggested a link between breast cancer and meningioma risk related to the role of hormones.
An inherited nervous system disorder: The rare disorder neurofibromatosis 2 increases the risk of meningioma and other brain tumors.
Obesity: A high body mass index (BMI) is an established risk factor for many types of cancers, and a higher prevalence of meningiomas among obese people has been observed in several large studies. But the relationship between obesity and meningiomas is not clear.
