Brain Cancer: Risk Factors

Print

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 brain tumors.

Family History

Though rare, a small number of families have been found to have several members with brain tumors.
