Mast Cell Tumors are the most frequently recognized malignant or potentially malignant tumors of dogs.
Many breeds appear to be predisposed, especially Boxers, Pugs, Rhodesian Ridgebacks, and Boston Terriers.
This cancer type may affect dogs at any age, but is more common in dogs 8 years of age or older.
These tumors may develop anywhere on the body as well as in internal organs.
These tumors may develop in multiple areas of the body (at once), in which they typically appear as raised, nodular masses that can be soft or solid upon touch.
The tumors may vary widely in size, and appearance alone cannot establish a diagnosis of the disease.
Clinical signs of illness can be seen in affected dogs and can include gastrointestinal problems.
Diagnosis of these tumors can be difficult, yet aspiration and cytology seems to be the number one choice if cancer is suspected.
Treatments include wide, deep surgical removal of the tumor and surrounding tissues, followed by radiation therapy - which may be curative if the number of remaining tumor cells in the affected area is small.
