Overview

The cause of primary brain tumors is unknown. There are many possible risk factors that could play a role.

Radiation therapy to the brain, used to treat brain cancers, increases the risk for brain tumors up to 20 or 30 years afterwards.
Exposure to radiation at work or to power lines, as well as head injuries, smoking, and hormone replacement therapy have NOT been proven to be risk factors.
The risk of using cell phones is hotly debated. However, most recent studies have found that cell phones, cordless phones, and wireless devices are safe and do not increase the risk.
Some inherited conditions increase the risk of brain tumors, including neurofibromatosis, Von Hippel-Lindau syndrome, Li-Fraumeni syndrome, and Turcot syndrome.
Lymphomas that begin in the brain in people with a weakened immune system are sometimes linked to the Epstein-Barr virus.
