Introductions to several of the most common tumors in dogs and cats.
Bone Tumors in Dogs Most primary bone tumors in dogs are malignant, and approximately 85% are osteosarcomas. Osteosarcomas are highly aggressive tumors, characterized by local invasion/destruction and distant metastasis (spread to other organs)
Feline Mammary Tumors Mammary cancer is the third most common cancer in cats. The average age of affected cats is 10-11 years of age. Almost 90% of feline mammary tumors are malignant, meaning they have the potential to spread to other portions of the body.
Lymphosarcoma in Cats Lymphosarcoma (lymphoma) is one of the most common cancers diagnosed in cats. It is a cancer of the lymphocytes (a type of blood cell) and lymphoid tissues. Lymphoid tissue is normally present in many places in the body including lymph nodes, spleen, liver, gastrointestinal tract and bone marrow.
Lymphosarcoma in Dogs Lymphosarcoma (lymphoma) is the third most common cancer diagnosed in dogs. It is a cancer of lymphocytes (a type of blood cell) and lymphoid tissues. Lymphoid tissue is normally present in many places in the body including lymph nodes, spleen, liver, gastrointestinal tract and bone marrow.
Tumors of the Nasal Passages in Dogs Tumors of the nasal passages and sinuses account for 1-2% of all cancers in dogs. These tumors tend to grow into surrounding tissues, but have a low chance of spreading (metastasis) to other parts of the body. When they do spread, the most likely sites are the regional lymph nodes and the lungs.
