The goal of behavioral oncology is to understand and explain the role and impact of behaviors at all phases in the cancer trajectory -- from prevention and detection to diagnosis and early treatment, to survivorship, recurrence, and/or death. Each chapter includes summaries of recent research on cancer-related behavioral interventions, discussions of the studies summarized, and suggestions for future research. The book is a product of collaboration among members of the Behavioral Cooperative Oncology Group of the Mary Margaret Walther Program for Cancer Care Research at the Walther Cancer Institute in Indianapolis, Indiana.
