October is Pet Cancer Awareness Month, a time to spread awareness of the disease and its treatments. Pets can get cancer just like people do, and it’s important to be aware of the symptoms and know what options are available to you if your pet is diagnosed with cancer. There are many different types of cancer that can affect pets, so it’s important to learn as much as possible about the disease. Treatment options vary depending on the type of cancer, but there are many ways to treat pet cancers successfully. If you think your pet may have cancer, don’t hesitate to see your veterinarian for a diagnosis. 

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.
  • 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.
  • 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.
