This volume addresses the critical need for standardized classification of rodent tumors, specifically focusing on rats, to facilitate comparative research and accurate diagnosis in oncology and toxicology studies. As part of a larger international effort, this fascicle provides a detailed compendium of tumor types observed in rats, drawing upon extensive pathological data and expert consensus. The work aims to establish a unified nomenclature and diagnostic criteria essential for reproducible scientific investigation.

This fascicle is recognized as a foundational reference within the fields of experimental pathology and toxicology, providing essential standardized terminology for rodent tumor classification. Its detailed approach and reliance on international expert consensus make it an indispensable tool for researchers and diagnosticians working with rat models. The work's utility lies in its ability to ensure consistency and comparability across studies, thereby advancing the understanding of carcinogenesis and the evaluation of potential carcinogens.
