Raise Awareness

Brain Tumor Awareness Month Proclamation

Congressional resolutions marking Brain Tumor Awareness Month were first passed by Congress in 2008. NBTS continues to work with our volunteer advocates each year to renew these calls for public awareness of brain tumors and to honor everyone who has faced this disease.

The resolutions serve as a commitment to every family who has lost someone and to every American who receives this frightening diagnosis that Congress continues to support research funding as the best means of advancing knowledge and treatment of all brain tumors.
