Abstract

This article focuses on the role of information disorders in media coverage of cancer as a growing public health problem on both sides of the Atlantic. Taking the examples of Chile and Spain, we analysed news (n = 5522) published by major digital newspaper outlets in both countries between 2020 and 2022 to explore the elements of contextual information disorders, the over- and/or under-representation of mentions of sources and actors, and major latent topics in both journalistic systems. To achieve these objectives, we employed topic modelling and coherence techniques. The results revealed a high number of references to institutional, administrative, and political sources and actors, followed by mentions of issuers of strategic communication and, less frequently, patients’ associations. The discourses differed in their underlying topics, with risk factors and psycho-social factors being the most frequently addressed in the Spanish press and geo-political and institutional health contexts being the most frequently mentioned in the Chilean press. The topic of advances in research, however, was common in both journalistic systems. This article closes by identifying future challenges in health communication.
