Abstract

Cancer is increasingly recognized as an emerging concern in wildlife health and biodiversity conservation in the Anthropocene. Although traditionally viewed as an individual disease associated primarily with aging, wildlife cancer is shaped by complex interactions among environmental changes, species-specific evolutionary adaptations, and ecological processes. This review synthesizes current knowledge on the ecological and evolutionary drivers of wildlife cancer by integrating evidence from comparative oncology, environmental toxicology, wildlife pathology, and conservation biology. We examine how anthropogenic stressors, including pollution, habitat degradation, climate change, and infectious agents, influence cancer susceptibility in wild populations, and summarize intrinsic mechanisms underlying interspecific variation in cancer vulnerability, including Peto's paradox, enhanced tumor suppression, and adaptive immune surveillance. We further highlight major methodological challenges, including limited surveillance capacity, fragmented datasets, taxonomic biases, and insufficient integration between cancer biology and conservation science. Finally, we discuss emerging interdisciplinary approaches, such as standardized monitoring frameworks, multi-omics technologies, artificial intelligence-assisted diagnosis, and One Health-based strategies, to advance wildlife cancer research and management. Collectively, this review positions wildlife cancer as an important ecological and evolutionary phenomenon and provides perspectives for incorporating cancer surveillance into biodiversity conservation and ecosystem health assessment.
