The primary mission of the ONS is promoting excellence in oncology nursing. In its efforts to accomplish this mission, the undertreatment of cancer pain has emerged as a significant issue for clinicians, educators, researchers, and administrators involved in the care of people with cancer. In an effort to promote cancer pain relief, the ONS contributes human, administrative, and financial resources from its existing organizational structure, personnel, and volunteers in the variety of ways described above. The structure of the ONS enables it to support the goal of cancer pain relief from the broadest of policy-making activities nationally to the provision of care by a nurse to a patient and family. The ONS Position Paper on Cancer Pain, other position papers and statements, adopted resolutions, and the strategic planning process will continue to guide the ONS's commitment and contributions to promoting cancer pain relief.
