Go Gray in May

remind me

Come together for Brain Tumor Awareness Month, a time dedicated to supporting, empowering, and amplifying the voice of the brain tumor community.

Three Days. One Mission.

This May 5-7, join us in Washington, D.C., to raise funds and awareness for the brain tumor community. Walk or run in Race for Hope DC; connect with patients and caregivers from across the country; and meet with your representatives in Congress at Head to the Hill to advocate for patient-first policies and urgently needed funding for brain tumor research.

Join Us This May

The brain tumor experience is full of extraordinary challenges and extraordinary hope. The gray area that falls in between is what drives us, unrelentingly, toward our mission of conquering and curing brain tumors — once and for all. As the National Brain Tumor Society, we offer a variety of ways to #GoGrayinMay, from advocating to Congress for better policies to participating in events (race, walk, or ride) that raise urgently needed funds to sharing your story to raise awareness and foster community.
