Mouth Cancer (Melanocytic) in Cats




After reaching a definitive diagnosis and careful evaluation, your cat’s veterinarian, in consultation with a veterinarian oncologist, will plan surgery to excise the tumor mass along with part of the bone involved. Your veterinary oncologist will also suggest chemotherapy in combination with radiation therapy to further enhance the treatment's effectiveness. Soft foods are recommended after surgery to prevent tumor ulceration and to ease out ingestion of food.


Living and Management


Prognosis depends upon the stage, location, extent of metastasis, and extent of the tumor mass removed during surgery. Unfortunately, the overall prognosis in most cats is not good and most die due to rapid loss of body weight, an inability to swallow correctly, and the spread of the tumor. Treatment, therefore, is directed toward improving the animal's quality of life.


After surgery, you should expect your cat to feel sore. Your veterinarian will give you pain medication to help minimize your cat’s discomfort, which should be used with caution (one of the most preventable accidents with pets is overdose of medication). Follow all your veterinarian's directions carefully and limit your cat's activity while it heals, setting aside a quiet place for it to rest away from household activity, children, and other pets.


It is important to monitor your cat's food and water intake while it is recovering. Due to involvement of the oral cavity, these patients are not able to take feed for number of days. Your veterinarian will devise a diet plan, which will include highly palatable and nutritious foods. As affected cats already have a tendency to lose weight, providing food to keep body weight within normal range is of utmost importance. 


In addition, chemotherapy medications have the possible toxic side effects, so your veterinarian will need to closely monitor your cat's stability, changing dosage as necessary. He or she will also conduct routine X-rays of the skull and lungs, and ask you to bring the cat in for regular evaluation visits to check progress and for recurrence.
