The Most Common Tumors in Dogs & Cats // Vet Med Explained

What is that lump on your dog or cat? 🐶🐱 In this video, we break down some of the most important masses seen in veterinary medicine, including lipomas, mast cell tumors, soft tissue sarcomas, mammary tumors, feline mast cell tumors, and feline injection-site sarcomas. We cover where these masses commonly occur, how they develop, what veterinarians see on fine-needle aspirates and histopathology, tumor grading and staging, prognosis, surgical margins, medications, chemotherapy, radiation therapy, and other treatment options. One of the biggest lessons: a mass is a physical finding—not a diagnosis. A harmless-looking lump can be a benign lipoma, but a mast cell tumor can sometimes look almost identical. That is why cytology, biopsy, histopathology, and proper staging are so important.
