Brain Cancer: Risk Factors

Physicians rarely know the exact reason a person develops a brain tumor. While additional research is needed, studies have found the following to be recognized risk factors for brain tumors:

  • Ionizing Radiation: High levels of ionizing radiation (such as from high-dose x-rays and radiation therapy) have been shown to cause cell damage, resulting in increase risk for brian tumors.
  • Family History: Though rare, a small number of families have been found to have several members with brain tumors.
