What should laypersons know about cancer? Towards an operational definition of cancer literacy

Abstract

ObjectiveTo operationally define cancer literacy, understanding which aspects of cancer are important to be known by a layperson to be considered cancer literate. MethodsA Delphi study in three consecutive rounds was conducted among a panel of Swiss cancer experts (oncologists, GPs, nurses from oncology wards, social workers, public health experts). ResultsThe result of the Delphi process is a first operational definition of the concept of cancer literacy, a list of the aspects of cancer that, in the expert's view, laypeople should know to be considered cancer literate. ConclusionsWe have now an idea of what should be known about cancer. The study also provides us with some useful hints about what should be communicated about cancer, e.g. via public communication campaigns, school education, or media. Practice implicationsThe operational definition of the concept can be used for the development and the validation of a measure of cancer literacy, not anymore limited to basic literacy and numeracy skills.
