Summary. Ulan-Ude is included in the list of Russian cities with the most adverse environmental conditions. Oncologic pathology in structure of morbidity of small animals takes a significant place, therefore analysis of influence of ecological factors on the development of cancer is very actual. Authors found that benign tumors of epithelial and mesenchymal origin predominate in the structure of oncological diseases of dogs. Malignant tumors are mostly presented by mesenchymal tumors.
The main noted morphological changes are hemorrhagic or catarrhal-hemorrhagic gastritis and exogenous pigmentation of the lungs, indicating receipt of potentially carcinogenic substances by nutritional or aerogenic way.
Keywords: Ulan-Ude, ecology, oncology, dogs, morphological changes, potentially carcinogenic substances, benign tumors, malignant tumors, structure.
