Most of the nasal tumors found in dogs and cats are malignant (cancer), and common types of them are carcinomas, followed by sarcomas. In cats, squamous cell carcinoma in the nasal cavity and carcinoma in lymph node epithelial cells are more encountered. The typical symptoms of nasal cancer include nosebleeds, loss of appetite, seizure and misshapen nose, etc.
Although the cause of nasal cancer is not known, it may be a result of abnormal cell growth in the nasal cavity, lymph node, bones, and other cells. Apart from these, nasal cancer can also be affected by other factors, such as age, gender, living environment, being in contact with certain kinds of chemical substances or toxins, and regular infections resulting in chronic disease, etc.
The nasal cavity is a big air-filled space above and behind the nose. It consists of the air-filled fossae connecting to the nasal cavity. Commonly, the types of cancer found in this area are carcinomas and sarcomas. The carcinomas, including adenocarcinoma and squamous cell carcinoma, the subtypes can develop in nasal epithelial cells. In a part of sarcomas cancer, it regularly appears in both the nose connective tissue and the cartilage in the nasal cavity.
