Neoplasia has been recorded in the vast majority of metazoans. The frequent occurrence of
cancer in multicellular organisms suggests that neoplasia, similar to pathogens/parasites …

Cancer is ubiquitous in wildlife, affecting animals from bivalves to pachyderms and
cetaceans. Reports of increasing frequency demonstrate that neoplasia is associated with …

Ecological and evolutionary concepts have been widely adopted to understand host–
pathogen dynamics, and more recently, integrated into wildlife disease management …

Cancer is pervasive across multicellular species, but what explains differences in cancer
prevalence across species? Using 16,049 necropsy records for 292 species spanning three …

Until recently, cancer in wildlife was not considered to be a conservation concern. However,
with the identification of Tasmanian devil facial tumour disease, sea turtle …

Growing evidence indicates that human activities are causing cancer rates to rise in both
human and wildlife populations. This is due to the inability of ancestral anti‐cancer defences …

Naturally occurring cancers in non-laboratory species have great potential in helping to
decipher the often complex causes of neoplasia. Wild animal models could add substantially …

While it is generally known that the risk of several cancers in humans is higher in urban
areas compared with rural areas, cancer is often deemed a problem of human societies with …

Based on the abundant studies available on humans showing clear associations between
rapid environmental changes and the rate of neoplasia, we propose that human activities …
