Delineating the role of binge eating in cancer research.

Purpose: Binge eating is defined as consumption of a large amount of food accompanied by a sense of loss of control over eating. While binge eating is associated with poor physical, behavioral, and psychosocial health, it has not been studied in cancer research. Therefore, the overarching goal of this review is to delineate the role of binge eating in cancer research and to spur new research in this area. Specifically, in this review, we outlined (1) binge eating as a possible risk factor that contributes to cancer risk, (2) how binge eating may develop after cancer diagnosis, and (3) how binge eating may be associated with health and relapse during survivorship.
Conclusions: It is critical to elucidate the role of binge eating in the prevention of cancer and long-term cancer survivorship. This review suggested a number of ways that binge eating may increase risk for cancer as well as several pathways that may lead to the development of binge eating after cancer diagnosis.
