Oncology is the study of cancer. Ten common signs of cancer in animals are abnormal swellings that persist or continue to grow, sores that do not heal, weight loss, loss of appetite, bleeding or discharge from any body opening, offensive odor, difficulty eating or swallowing, hesitation to exercise or loss of stamina, persistent lameness or stiffness, difficulty breathing, urinating, or defecating. With prompt diagnosis and treatment, many cancers which were considered untreatable just a few years ago are now treated with better, more predictable outcomes. Oncology patients at PVS have available the most current and effective forms of therapy that focus on providing the best quality of life for your pet. For more detailed information about cancer treatment see our Cancer articles in the Library section.
