If you find a new lump on your dog you should of course have a veterinarian check it out to play it safe. But know that the majority of lumps and bumps on your dog’s skin are benign. Even a significant number of lumps under your dog’s skin are benign. If a bump is found to be cancerous, that doesn’t mean your pet is going to die from it. That’s because most of the cancerous masses on a dog’s body are non-metastatic, meaning they won’t spread to distant sites in the body. Granted, they can invade healthy tissue locally and thereby become life-threatening. But they’re most often not fatal if they’re treated without delay. That’s why anything at least a centimeter in diameter (a quarter of an inch) should be brought to the doc-
tor’s attention.
