What are the risk factors for a brain tumor?

Studies have found the following risk factors for brain tumors:

  • Ionizing radiation: Ionizing radiation from highdose x-rays (such as radiation therapy from a large machine aimed at the head) and other sources can cause cell damage that leads to a tumor. People exposed to ionizing radiation may have an increased risk of a brain tumor, such as meningioma or glioma.
  • Family history: It is rare for brain tumors to run in a family. Only a very small number of families have several members with brain tumors.

Researchers are studying whether using cell phones, having had a head injury, or having been exposed to certain chemicals at work or to magnetic fields are important risk factors. Studies x0060have not shown consistent links between these possible risk factors and brain tumors, but additional research is needed.

This answer is based on source information from the National Cancer Institute.

The risk factors for brain tumors are radiation and smoking, but they can occur with no known cause.
