As the care of children with cancer and their families becomes ever more complex and demanding, it is apparent that the specialty of paediatric oncology nursing is exploring and pushing the boundaries of practice. Nowhere is this more apparent than in the development of new roles and new ways of thinking and doing. This book offers a timely exploration of the history and development of new roles, based on current examples from practice. The book also shares ongoing research work to underpin these developments from an evidence-based perspective. Key issues are explored in relation to the complexities of professional practice, the influence of service delivery, and the role of education in supporting and developing practice in order to offer the reader an holistic overview of current perspectives in paediatric oncology nursing.
