Welcome to LIVESTRONG at School™! Created by Scholastic and the LIVESTRONG Foundation, the LIVESTRONG at School program uses national standards-based lessons to teach your students about the realities of cancer. While it is a difficult subject to talk about with kids, the LIVESTRONG Foundation believes that it is important for students to understand what cancer is and how it can be treated.
