10 Biggest Early Warning Signs of Cancer in Dogs

2. Persistent Lumps or Bumps: When to Worry

Not all lumps and bumps on a dog are cancerous, but they warrant attention, especially if they persist or grow over time. A lump that changes in size, shape, or texture should be evaluated by a veterinarian. Some cancers, like mast cell tumors, can appear as small, benign-looking bumps but are aggressive in nature. Regularly checking your dog for new lumps and monitoring existing ones is a proactive way to catch potential issues early. Veterinarians often recommend a fine needle aspirate or biopsy to determine the nature of the lump. Early identification and diagnosis can lead to more effective treatment options and better outcomes for your pet.
