Hey everyone, I need someone who's had been treated from brain cancer, Medulloblastoma, with the Chemotherapy and radiation. What are the side affects?? my brother is 8 almost 9, and we discovered that he had brain cancer about a week ago, it's hard, but it's harder on my parents of course, I want anyone to tell me the possible side affects he might get. The doctor already told us, but it doesn't hurt to hear what other people has to say. Please help me
