Abstract

The National Cancer Institute’s Office of Cancer Survivorship (OCS) leads efforts to define and address the complex and evolving needs of cancer survivors, caregivers, and families through research, care, collaboration, and advocacy. This article provides updated definitions for key terms—cancer survivor, survivorship, survivorship care, and survivorship research—to guide practice, policy, and research in improving outcomes across the cancer care continuum.
