The American Psychosocial Oncology Society (APOS) was formed in 1986 to bring together professionals working in the psychological, behavioral and social aspects of cancer. Its mission broadened in the early 2000s to network professionals from all disciplines working in psychosocial oncology. Over five hundred psychosocial oncology professionals gather at APOS' annual conference to share new research and clinical innovations. The Psycho-Oncology journal was begun in 1992 to publish research specific to psychosocial oncology in one journal.
