About

Nursing is a calling. And oncology nursing is a calling like no other. The collective, specialized experience and expertise that our nurses possess has the power to transform cancer care for the better, forever.

This is the reason for the Oncology Nursing Society (ONS) to be. ONS provides these amazing women and men with a community where they can learn, share, and flourish. Where they have a voice. And where they are celebrated.

The enormous contributions that our nurse members, nurse scientists, and nurse teachers have made since our inception in 1975 has made the Oncology Nursing Society who we are today: the standards bearer of advanced cancer care.

Through ONS, cancer caregivers at any point on the clinical ladder are able to advance their learning and careers, understand and contribute to oncology science and best practices, advocate for their profession, and ultimately advance our cause—to continuously improve the quality of cancer care and the lives of every nurse who provides it.


The ONS is a professional association of more than 35,000 members committed to promoting excellence in oncology nursing and the transformation of cancer care. With minds that never stop learning. With hearts that never stop caring. With you, we are transforming cancer care for the better, forever.
