To lead the transformation of cancer care

Core Values

Values are guiding principles for our organization, our leaders, and our members.


ONS and its members face every endeavor with knowledge and learning. We strive to apply our broad perspectives consistently while leading the transformation of cancer care.


We strive to foster excellence in oncology nursing and quality patient care. We are committed to nothing less than excellence in our organization and the care of patients.


We, as an organization and as individuals, advocate on behalf of people with cancer to ensure their quality of life and access to exemplary care throughout the continuum of life. We advocate on behalf of patients and the profession to ensure respect and recognition, access to education, safe working environments, and fair reimbursement. We also serve as advocates for public health policy.


Our organization is stronger when we appreciate the diverse backgrounds and invite the diverse perspectives of our membership and staff.

As a membership organization, we are committed to respecting, accepting, and embracing the diversity of all our members, their employers, volunteers, employees, and other stakeholders. We empower everyone to succeed by promoting inclusive environments and equitable treatment through our chapters, events, resources, and workplaces.
