Ella overhears her parents talking. It sounds like something is wrong with Dad. She decides to make a checklist for Dad to find out if he is okay. Her parents later explain that Dad has cancer. Ella struggles through her emotions as she learns about cancer treatment, cancer prevention, and the role of genetics. This book will serve as a valuable resource for those who need to discuss a cancer diagnosis with children. By explaining -- in simple language with engaging illustrations-- what cancer is and what one can expect when diagnosed, A Checklist for Dad will aid parents in providing their children with much needed information and comfort in a format that is familiar to them. In addition to parents, health providers, counselors, teachers, and librarians can use this text to discuss the topic of cancer in a straightforward yet gentle manner. This is the first children's book published by the International Agency for Research on Cancer (IARC). Proceeds from the sale of the book go to the Education and Training Group at IARC to support courses, fellowships, and training of cancer researchers worldwide.
