Risk Factors

Age – While there are certain types of brain tumors that are more common in children, the risk of adult primary brain tumors increase with age and more commonly seen in older adults.

Radiation Exposure – Ionizing radiation, which includes previous radiation for cancer treatment, has been shown in some studies to link to some forms of brain cancer.

Genetics – A small percentage of some brain tumors has been linked to possible genetic factors. These are usually associated with certain cancer predisposition syndromes such as Li-Fraumeni syndrome, neurofibromatosis, tuberous sclerosis, and Turcot’s syndrome. Scientists are still studying the correlation and prevalence of family clusters of certain types of brain cancers to determine their cause.
