Cancer in Pets
Cancer is a leading cause of disease-related death in older pets. Just as in humans, early detection can make the difference in treatment options and outcomes. Regular health exams—at least once per year for younger pets and twice per year for pets over 7—can help detect issues while still in the early stages, improving treatment options for your pet.
Your observations of your pet's behavior and health are important. If you notice any of these signs in your pet, please consult with your veterinarian.
Do not assume your pet has cancer if they show some of these signs. Symptoms such as bad breath and weight loss can be signs of other health problems, too. That's why it's best to have your pet seen by its veterinarian.
When in doubt, check it out.
