Behavioral medicine, cancer control, and NCI: reflections on a fruitful past and auspicious future.

Cancer prevention and control has benefited substantially from behavioral medicine research over the last several decades. The National Cancer Institute's (NCI) Division of Cancer Control and Population Sciences, ably led by Barbara Rimer and then Bob Croyle since being established in 1997, has been a primary supporter of this research. NCI has made significant investments in many of the topics featured in this special section and will continue to do so. These include research on basic behavioral processes such as affect as well as optimal approaches to health communication. A key and enduring focus has been the support of behavioral interventions, particularly for tobacco, diet, physical activity, and sun exposure. The success of such interventions will be amplified to the extent that they leverage novel research designs, emerging digital technologies, evidence gleaned from the burgeoning field of implementation science, and lessons learned from greater attention to the impact of health disparities and inequities. Moreover, as the cancer survivor population continues to grow given the rapid development of diagnostic and therapeutic science, it will be even more essential to devote attention to understanding and addressing the health care and other needs of survivors such as cognitive dysfunction and financial toxicity. The field of behavioral medicine should be both applauded for its many contributions to reducing the cancer burden and encouraged to continue developing new research ideas in these critical areas.
