Odontogenic fibromas, sometimes previously referred to as an epulis, are benign tumors of the mouth often at the front of the upper jaw. These may be locally invasive and may cause some oral pain. Surgery is the recommended course of action to treat this condition.
-
Oral squamous cell carcinomas (SCC) are the most common oral tumor in cats, and second most common in dogs. These tumors are locally aggressive, with a possibility to metastasize. Regardless of the location of SCC, surgery is the typically the standard treatment. Radiation therapy may be recommended following surgery or as a primary treatment for palliative care. Staging is recommended for all cases. If metastasis is present chemotherapy is often pursued.

Fibrosarcomas are the second most common oral tumor in cats and arise from the fibrous and connective tissues of the oral cavity. These tumors are very invasive locally and are often difficult to manage, Diagnosis is based on biopsy and treatment involves surgery and occasionally radiation or chemotherapy. Palliative care with pain relief and antibiotics are essential to improve quality of life.

The most common oral tumor seen in cats is squamous cell carcinoma; the second most common is fibrosarcoma. This handout discusses the clinical signs, diagnosis and treatment of oral tumors in cats.
-
This handout discusses some of the more common forms of oral tumors in pets. Highlighted are Papillomas (“Warts”) and Fibropapillomas, both of wish are caused by viral infection. Clinical signs, diagnostic methods, and treatment options are highlighted.

Osteosarcomas are somewhat rare in cats and progress slowly. Osteosarcoma is very painful. The most common location where osteosarcomas develop in cats is the hindlimb. Amputation is by far the most common treatment. Chemotherapy is not generally pursued without evidence of metastasis, given the relatively long-term control with surgery alone.

Ovarian tumors are quite rare in North American pets, mainly due to routine spaying practices. This handout discusses ovarian tumors in dogs and cats. The various forms of ovarian tumors, clinical signs, diagnosis, treatment, and prognosis of this cancer are outlined.

Most cats instinctively hide their pain as a survival mechanism which can make detecting pain in cats a challenge. Although the signs may be subtle, careful observation of a cat’s everyday behaviors will often reveal pain when it is present. These signs may include changes in behavior, mobility, elimination, and grooming habits. Common pain medications include NSAIDs and opioids. Your veterinarian will choose the appropriate drugs based on your cat's specific needs.

Primary pancreatic tumors are rare in dogs and cats. Exocrine tumors include adenomas and adenocarcinomas, and endocrine tumors include insulinomas, gastrinomas, and glucagonomas. Insulinomas are the most common type of pancreatic tumor, followed by adenocarcinomas. Both tumors are more common in dogs than cats. Large breed dogs and Siamese cats may be predisposed. Insulinomas are usually diagnosed with the finding of hypoglycemia with normal to high insulin on bloodwork and concomitant clinical signs. Adenocarcinomas typically go undetected until the clinical signs of metastasis are evident. For both tumors, diagnostic imaging and exploratory surgery with tumor removal (or biopsy) and histopathology are needed for a definitive diagnosis. Insulinomas can be treated with surgery and chemotherapy. Surgery is possible with adenocarcinomas, but as the cancer is more diffuse and has usually metastasized by the time of diagnosis, the prognosis is poorer. Chemotherapy and radiation therapy are ineffective in the treatment of adenocarcinomas. Given the high rate of metastasis with these tumors, staging is recommended prior to surgery.

The pancreas is a vital organ on the right side of the abdomen adjacent to the stomach. It produces enzymes to assist in food digestion and hormones such as insulin, which regulates blood sugar or glucose metabolism. When the pancreas becomes inflamed, the condition is called pancreatitis. Common clinical signs include decreased appetite, nausea, vomiting, lethargy, diarrhea, and abdominal pain. If the attack is severe, acute shock or death may occur. Successful pancreatitis management will depend on early diagnosis and prompt medical therapy.
