Oral Tumors in Dogs & Cats in Beaverton, OR
Finding a lump or mass in your pet’s mouth is frightening. Oral tumors range from benign growths to aggressive cancers, and early diagnosis makes a significant difference in treatment options and outcomes. At Premier Pet Dentistry, Dr. Martin provides thorough evaluation, biopsy, and surgical treatment of oral masses — including advanced procedures such as mandibulectomy and maxillectomy.
Types of Oral Masses in Pets
The mouth is one of the more common sites for tumors in dogs and cats. Some masses are benign, such as certain epulides and gingival hyperplasia, while others are malignant, including oral melanoma, squamous cell carcinoma, and fibrosarcoma. Some benign growths can still invade bone locally and require surgical removal. Because masses cannot be identified reliably by appearance alone, a biopsy with histopathology is the key to an accurate diagnosis.
Signs of an Oral Tumor
- A visible lump or swelling on the gums, lips, tongue, or palate
- Loose or displaced teeth in one area
- Bleeding from the mouth or blood-tinged saliva
- Bad breath, drooling, or difficulty eating
- Facial swelling, a bulging eye, or nasal discharge
- Weight loss or reluctance to chew toys
Diagnosis and Treatment
Evaluation includes an oral exam under anesthesia, dental and skull x-rays, and a biopsy of the mass. Advanced imaging such as CT may be recommended to plan surgery, and chest imaging helps check for spread. Treatment through our oral medicine and oral surgery services may include excision of small masses, partial removal of the jaw (mandibulectomy or maxillectomy) for invasive tumors, and reconstruction. Dogs and cats adapt surprisingly well after jaw surgery and usually return to eating and playing comfortably.
Dr. Martin collaborates with your primary veterinarian and, when appropriate, oncology specialists to plan any additional care such as radiation or chemotherapy.

Oral Tumor FAQs
Are all oral masses in pets cancerous?
No. Many oral masses are benign, but some benign growths are locally invasive and some masses are malignant. A biopsy is the only reliable way to know.
How quickly should an oral mass be evaluated?
As soon as possible. Smaller masses are easier to remove completely and often have a better prognosis.
Can my pet eat normally after jaw surgery?
Most dogs and cats adapt very well after mandibulectomy or maxillectomy and return to eating, drinking, and playing comfortably.
Will my pet look different after surgery?
There may be some change in facial appearance, but most owners find it is far less noticeable than they expected, and their pet’s quality of life improves.
Does Premier Pet Dentistry work with oncologists?
Yes. When additional treatment such as radiation or chemotherapy may help, we coordinate with your primary veterinarian and veterinary oncology specialists.
What is histopathology and why is it needed?
Histopathology is the microscopic examination of tissue by a pathologist. It identifies the type of mass and confirms whether surgical margins are clear.
