All unusual growths should be evaluated by your veterinarian, who will be able to evaluate the problem and determine if treatment is needed. At West Market Veterinary Hospital in Greensboro, NC, we offer treatment of internal and external mast cell tumors in cats.

What Are Mast Cell Tumors?

Mast cells are common in the body, especially in the skin. These cells are important to immune system function, but they can sometimes experience abnormal growth, leading to internal or external tumors that release histamines in the animal’s body. Mast cell tumor growth is common in both dogs and cats. 

External Mast Cell Tumors

You may find a lump on your cat’s skin that increases over time. The growths may seem inflamed or itchy. Generally, these growths are benign and require simple removal by a veterinarian. Mast cell tumors produce histamines that can be hazardous for the animal, so antihistamine medications are administered. External mast cell tumors can sometimes metastasize deeply into tissues, making surgical removal more difficult. Chemotherapy may be recommended to halt the spread of the tumor.

Internal Mast Cell Tumors

Internal mast cell tumors can be more difficult to diagnose. Symptoms of internal mast cell tumors may include vomiting, diarrhea, or loss of appetite. These symptoms should signal a trip to your Greensboro vet to have the problem investigated. Most frequently, internal mast cell tumors will develop on the gastrointestinal tract or spleen. As with external tumors, antihistamines may be given to reduce symptoms. Your veterinarian will determine if the tumor is benign or malignant, as well as what stage the cancer is to determine how far the disease has progressed. Surgery is the standard treatment for internal mast cell tumors. Chemotherapy is often administered after surgical removal of the tumor to prevent recurrence.
