A risk factor is anything that increases a person’s chance of developing a tumor. Although risk factors often influence the development of a tumor, most do not directly cause a tumor. Some people with several risk factors never develop tumors, while others with no known risk factors do. However, knowing your risk factors and talking about them with your doctor can help you make more informed lifestyle and health care choices.
The risk factors for meningioma include:
Age. Adults between 30 and 70 are most likely to be diagnosed with meningioma. Children rarely develop meningioma.
Gender. Women are more than twice as likely as men to develop meningioma; however, men are three times as likely as women to be diagnosed with malignant meningioma.
Radiation exposure. High-dose radiation to the head may increase a person’s risk of developing meningioma. Also, low-dose radiation such as in the treatment of tinea capitis (ringworm of the scalp) or through dental x-rays may increase a person’s risk of developing meningioma decades after treatment.
Genetic disorders. People with neurofibromatosis type 2  (NF2) have a higher risk of developing meningioma. People with NF2 are also more likely to develop malignant or multiple meningioma (more than one tumor).
Race/Ethnicity. In the United States, black people have higher rates of meningioma than white people. Meningioma is more common in Africa than in North America or Europe.
At this time, there are no known ways to prevent meningioma.
