A recent study points to an alarming figure: more than 250,000 scientific articles related to cancer could have been completely fabricated between 1999 and 2024. This production is increasing and threatening honest scientific output.
Generating knowledge through scientific research results in intense competition between teams and individuals, where a publication in a prestigious journal can alter the course of a career. Despite many questioning the current rules of this competition, evaluating the quality of a researcher primarily relies on the number of publications, their impact measured by the volume of citations they generate, and the prestige of the journals they are published in. The significance of these indicators in securing rare funding and advancing individual careers contributes to encouraging behaviors contrary to scientific integrity, such as resorting to fraudulent practices.
This context has led to the rise and rapid growth of specialized organizations in the sale of fake scientific articles, known as “paper mills” or article factories. These organizations are suspected of producing thousands of articles over the past decade, compromising significant portions of the scientific literature. In a study published in the British Medical Journal in January 2026, it is estimated that over 250,000 scientific articles related to cancer could have been completely fabricated between 1999 and 2024.
While these articles represented less than 1% of annual scientific publications in 1999, their rate has now escalated to 15% of the content produced each year. The fight against cancer research is at risk: false publications are spreading, and an intensification of this problem is anticipated.
The “article factories” produce and sell fake scientific articles in nearly industrial quantities. They even utilize traditional marketing techniques, advertising online and allowing clients to choose their position in the list of authors of a prefabricated article, with the first and last positions perceived as more prestigious. The service’s cost can range from hundreds to thousands of euros, with suspicions that some “article factories” may even provide a “post-sale service” by offering corrections or responding to reader comments after publication.
The number of publications attributed to “article factories” surged in the early 2010s, indicating the existence of a large-scale fraudulent system. The collaboration between manufacturers and unscrupulous publishers significantly accelerates the pace of fraudulent article publication, surpassing that of authentic articles.
These factories derive their productivity from predefined writing templates, often reusing text and image fragments from their past productions. This method has facilitated the publication of articles with similar structures, containing the same phrasing, experimental schemas, and methodological or stylistic errors in the biomedical literature, notably in cancer research.
###KEY POINTS: – A study reveals that over 250,000 scientific articles related to cancer could have been fabricated between 1999 and 2024. – The rise of specialized organizations selling fake scientific articles threatens legitimate scientific output. – The production of fraudulent articles at an industrial scale poses serious problems for the integrity of scientific research, particularly in cancer studies.
