Cerumenogram is the name given to a Brazilian research field that investigates cerumen as a biological matrix for identifying chemical signatures associated with metabolic changes and, in particular, cancer. Developed by researchers affiliated with the Federal University of Goiás, especially Nelson Roberto Antoniosi Filho and his collaborators, the approach gained visibility following the publication of a study in Scientific Reports in 2019 and returned to public attention through news coverage and volunteer recruitment initiatives in the years that followed.

Beyond the novelty of using earwax as a basis for diagnosis, interest in the subject comes from the combination of scientific inventiveness, low invasiveness, and the ability to attract international attention to research developed outside the most established centers of global science. Its projection lies less in widespread adoption and more in the recognition of an original Brazilian idea with the potential to broaden perceptions of the biomedical innovation being produced in the country.

Presence Indicators:

• Publication in a high-profile international journal, providing the research with an entry point into global scientific circulation.
• Renewed coverage in Brazilian news outlets in 2025 and 2026, signaling a resurgence of public and journalistic interest.
• The existence of an institutionalized project at UFG, including an FAQ and volunteer recruitment, indicating continuity rather than a brief moment of attention.
• The participation of Amaral Carvalho Hospital and references to international media coverage reinforce the research’s ability to extend beyond its local context.
