Psycho-Oncology is the official journal of the American Psychosocial Oncology Society and the British Psycho-Oncology Society concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process.
