The incidence of neuroendocrine tumors (NETs) has increased multiple fold in the last 4 decades, providing more impetus for clinicians to understand the heterogeneity of NETs and to be able to recognize and treat these tumors effectively. For this reason, the editors of this book sought to provide a resource to those clinicians interested in this field. In this book, a diverse group of authors provides a multidisciplinary approach to the management of NETs, an understudied group of tumors. This book addresses the more commonly encountered scenarios as well as unusual challenges that may arise in the clinical course.
