👉 Mesocaecal is a term used in veterinary medicine to describe an animal that has lost its ability to digest large amounts of food and to become malnourished. This condition can be caused by various factors such as genetic defects, nutritional deficiencies, or environmental stressors. In the context of mesocarcinogenesis (the development of cancer), a mesocaecal tumour is a type of tumour that arises from the mesocarcinoma, which is a precursor to cancer.
