Section: Overview
Primary lung tumors are cancers that arise in the lung tissue of both dogs and cats. They are rare in both species, but slightly more common in dogs.The most common type of tumor is a carcinoma. Carcinomas are malignant tumors that develop from the epithelial tissues in the lungs. They may be primarily derived from the lung tissue itself, or the airways or bronchioles.The exact cause of lung cancer is not known, but there appears to be an increased incidence of cancer in dogs that live in urban environments, as well as dogs that are exposed to second hand smoke. Lung cancer is generally diagnosed in older animals, with an average age of about 11 years, but it can also be seen in younger pets.What to Watch For
