Explaining a diagnosis of cancer to children or teenagers can feel difficult and overwhelming. This book is designed as a starting point for having this conversation. Talking sensitively and honestly about the diagnosis can provide children with reassurance during a time of uncertainty and change. This book focuses on when a parent has cancer, but much of the discussion will be relevant for anyone who needs to explain a cancer diagnosis to children or teenagers - for example when a child's sibling or friend has cancer, when their grandparent or another significant adult has cancer, or when a child has cancer. Different chapters offer tips on talking to children of different ages throughout all stages of cancer and includes quotes and stories from people who have been affected by cancer.
