10 Apr Oral Tumors in Dogs and Cats: What to Watch For
Oral tumors can occur in both dogs and cats, and while that may sound scary, early detection can make a big difference in treatment and outcomes. These growths are often found during routine veterinary exams or when pet owners notice subtle changes at home. Knowing what to look for and acting on it can help catch problems sooner, when more treatment options are available.
Signs of Oral Tumors in Dogs and Cats
One of the most common early signs is bad breath that seems worse than usual. While “dog breath” isn’t always pleasant, a sudden or severe change can be a red flag. Other symptoms to watch for include:
- Trouble eating or chewing
- Weight loss
- Drooling or blood-tinged saliva
- Swelling around the face or mouth
- Visible lumps or growths in the mouth
It’s important to remember that these signs don’t always mean cancer. Dental disease, infection, or inflammation can look very similar. However, any of these changes should prompt a visit to your veterinarian for a closer look.
Routine dental cleanings are one of the best tools we have for early detection. Because pets are under anesthesia, veterinarians can perform a thorough oral exam and identify concerns that may not be visible during an awake exam.
Are All Oral Tumors Cancerous?
Not all oral tumors are cancerous. They can be either benign (non-cancerous) or malignant (cancerous), and the behavior of each type of oral tumor is very different.
Benign tumors do not spread to other parts of the body, but they can still grow and affect nearby tissue or bone. Malignant tumors, on the other hand, tend to be more aggressive. They can invade surrounding structures and, in some cases, spread to other areas of the body.
In dogs, benign oral tumors are seen more commonly. In cats, however, malignant tumors are unfortunately more frequent, which makes early evaluation especially important for feline patients.
How Are Oral Tumors Diagnosed?
It’s not possible to determine exactly what a mass is just by looking at it. A biopsy is needed to make a definitive diagnosis. This involves taking a small sample of the tissue and sending it to a pathologist for evaluation.
Advanced imaging is also an important part of the process. Cone beam CT scans allow us to see what’s happening below the surface. They help determine the size of the mass, whether bone is involved, and how far the disease may have progressed. This information is essential for planning the most effective treatment.
When to Take Action
If you notice anything unusual in your pet’s mouth, it’s always best to have it evaluated sooner rather than later. Early diagnosis can significantly improve treatment options and outcomes.
