Many patients being treated for cancer have significant distress and often do not receive the attention they require. The psychosocial concerns of these patients are now better recognized and treated through psycho-oncology, which has become a multidisciplinary subspecialty of oncology concerned with the emotional responses of patients at all stages of disease, their families, and staff. In her presentation at the NCCN 18th Annual Conference, Dr. Jimmie C. Holland briefly reviewed the early role played by the NCCN as well as other national and international organizations in improving the psychosocial care of patients with cancer.
