Published on July 16, 2025 in Glioblastoma

Johnathan Masterson’s life was forever changed on the night of November 22, 2023, when a sudden, intense headache led to an ER visit and the devastating discovery of a mass on his brain — glioblastoma (GBM).

In this video, Johnathan shares his story from diagnosis to surgery and recovery, and how he’s using his voice and story to fundraise for the National Brain Tumor Society and create hope for others facing this disease.

For these hopes to be realized, breakthroughs can’t wait: we must keep the momentum going, and we need your help to do so. For everyone with a glioblastoma diagnosis, it’s time for a better chance.
