What are the risk factors for primary brain tumors?
Risk factors for some – but not all – primary brain tumors include:
- Having an immune system disorder like the Epstein-Barr virus or AIDS.
- Using immunosuppressants after an organ transplant.
- Genetic syndromes such as neurofibromatosis type 1 and type 2, von Hippel-Lindau disease, tuberous sclerosis, and Li-Fraumeni syndrome.
- Exposure to vinyl chloride.
Even so, most people with a primary brain tumor have no known risk factors.
