This paper reviews the major definitions of cancer survivorship. The current definition of a cancer survivor used in this new journal will consider many of the elements of cancer survivorship as described in these earlier definitions. It is expected that the details of the definition of cancer survivor will evolve as knowledge in the area increases... The Journal of Cancer Survivorship: Research and Practice will focus on research, academic discourse, and policy-related to adults living with a cancer diagnosis following primary treatment for cancer through the end of life.
