@castielvscancer: We are Castiel’s family. He has been fighting high-risk neuroblastoma his entire life. He is finishing his standard treatment — but the hardest part is still ahead. There is an experimental vaccine trial in New York City that could prevent the cancer from coming back forever. Insurance won’t cover it. We can’t do this alone. If you can’t donate, please share this video. Every comment, every like, every share helps more people see his story. Help us save our son.
