The main purpose of this book is to provide a source of information and guidance for children with cancer and for their families. It is intended to help them understand these new experiences and to reduce the fear that accompanies uncertainty. Structurally, the layout will serve as a roadmap, taking the child and his family from diagnosis through treatment to ultimate outcome, which more and more often is that of cure. It is also designed to be a resource for health care professionals who are unfamiliar with the area of pediatric oncology.
