There are no steps to keep growths in the brain from starting. Some risks can’t be changed, such as your race or age. Others can’t be avoided.

You may work in a job that puts you at harm. Check with the National Institute for Occupational Safety and Health or the Environmental Protection Agency for help on how to protect yourself.

If you have cancer, getting it treated will lower the chances of it spreading to the brain.

Talk to your doctor about your risks.
