About ONS

About ONS

The Oncology Nursing Society (ONS) is a professional association of more than 39,000 members committed to promoting excellence in oncology nursing and the transformation of cancer care.

Since 1975, ONS has provided a professional community for oncology nurses, developed evidence-based education programs and treatment information, and advocated for patient care, all in an effort to improve quality of life and outcomes for patients with cancer and their families. Together, ONS and the cancer community seek to reduce the risks, incidence, and burden of cancer by encouraging healthy lifestyles, promoting early detection, and improving the management of cancer symptoms and side effects throughout the disease trajectory.

How We Started

Former ONS logoONS traces its origin to the first National Cancer Nursing Conference, supported by the American Nurses Association and the American Cancer Society (ACS) 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, ONS has become a leader in cancer care. It has grown to include more than 225 local chapters and advocates for oncology nurses at the national level.
