Soon after Liz had a seizure at work, she was diagnosed with a brain tumor. In her personal blog, she started posting about what she was experiencing, with an unexpected consequence: people all over the world started sharing stories like hers. Soon, Liz’s blog, “The Liz Army” became a a place to share experiences, fears, motivations, and much more for a community of people with brain tumors and their caregivers. In this conversation we hear Liz’s story, how her online community began, and the role that all patient communities can play for each person facing a frightening diagnosis.
