Tumours in Laboratory Animals

Cancer is a complex disease and researches oriented towards learning more about its origin, development, types, progression and therapy are ever evolving. Animal studies remain essential to understand the mechanisms underpinning tumourigenesis, malignancy and to discover improved methods for tumour prevention, diagnosis, prognosis and therapy. Available literature was reviewed to collect some useful information about the spontaneously occurring and induced tumours in the laboratory animals including mice, rat, hamsters, guinea pigs and rabbits. These tumours included hepatocellular carcinoma, adenocarcinoma, nephroblastoma, squamous cell carcinoma, mammary gland carcinoma and others including both spontaneously occurring and induced ones.
