A groundbreaking new publication by the International Agency for Research on Cancer (IARC) has emerged, offering crucial insights on bias assessment in case–control and cohort studies. Titled *Bias Assessment in Case–Control and Cohort Studies for Hazard Identification* (Volume V in the renowned IARC Statistical Methods in Cancer Research series), this invaluable resource aims to educate epidemiologists and research professionals on how to navigate the complexities of confounding, information bias, and selection bias in their studies.

This comprehensive guide is tailored for individuals without extensive statistical backgrounds as well as statisticians seeking to deepen their understanding of epidemiological concepts. By breaking down intricate ideas into accessible formats, the publication equips researchers with practical methods to evaluate the potential impacts of biases on their findings, which is particularly vital in the context of cancer research.

What sets this publication apart are the plethora of real-world examples drawn from cancer epidemiology. These illustrations are designed to provide clarity on bias assessment, ensuring the information resonates with both seasoned researchers and newcomers in the field. Additionally, the resource includes online links to helpful coding tools and spreadsheets to facilitate the research process.

One of the publication's key contributions is the outlined integration process for bias assessments into broader evidence synthesis. This structured approach leverages the diverse methods discussed throughout the text, ensuring that comprehensive evaluations take into account all relevant studies—a critical aspect given the complexity of cancer epidemiology.

The development of this scientific publication was bolstered by a collaborative workshop, which brought together 37 experts from 12 countries to delve into the nuances of epidemiological bias assessment in hazard identification. This workshop was made possible with financial support from the United States National Cancer Institute, showcasing the collective commitment to improving research methodologies in cancer studies.

With the release of *Bias Assessment in Case–Control and Cohort Studies for Hazard Identification*, researchers and scientists alike now possess a powerful tool for enhancing the reliability and validity of their findings in the ongoing battle against cancer. The journey to unbiased research begins here!
