Oncology Nursing Society

The Oncology Nursing Society (ONS) is a nonprofit membership organization of more than 37,000 registered nurses and other healthcare providers in patient care, education, research, and administration in oncology nursing.

ONS traces its origin to the first National Cancer Nursing Research Conference, supported by the American Nurses Association and the American Cancer Society in 1973. Following this conference, a small group of oncology nurses met to discuss the need for a national organization to support their profession. Since its official incorporation in 1975, it has grown to include 231 chapters and 27 special interest groups. It provides information and education to nurses around the world. In addition, the society plays an active role in advocacy activities at the local, state, national, and international levels.
