Learn About Cancer in Pets
Despite incredible advancements in veterinary medicine, veterinary professionals are seeing more cancer in pets than ever before, which might be due in part to our beloved companions’ longer lives. The American Veterinary Medical Association (AVMA) estimates about one in four dogs will develop neoplasia at some point in their lives, and almost half over the age of 10 will develop cancer. Read on to learn more about cancer signs in your furry friend.
Common cancers in pets
Some of the most common types of cancer in pets include:
- Osteosarcoma — Osteosarcoma is a highly aggressive bone cancer that most commonly invades the limb bones in large- and giant-breed dogs. All too often, metastases to the lungs have formed by the time this cancer is diagnosed, making the prognosis a grim one.
- Mast cell tumors — More common in dogs than cats, these skin tumors can range from relatively benign if removed early, to seriously malignant and aggressive.
- Mammary gland cancer — Highly preventable through correctly timed spaying of female pets, mammary gland cancer is the most common tumor found in female dogs. Mammary tumors in cats are malignant 85% of the time; in dogs, they are cancerous about half the time.
- Hemangiosarcoma — This aggressive cancer affects vascular endothelial cells, with tumors most often occurring in the spleen or heart. Certain breeds are more predisposed than others, including boxers, German shepherds, Labradors, and golden retrievers.
- Lymphoma — Lymphoma is a cancer of the lymph system, which is part of the immune system. In cats, one in three cancer diagnoses is lymphoma, with the gastrointestinal tract most commonly affected.
