Mast-Cell Tumors

                       ----------------

                      General Information



Mast-cell tumors occur in both dogs and cats and may be either

non-cancerous (benign) or cancerous (malignant).  Their cause is

unknown, and they occur more frequently in Boxers, Boston

Terriers, English Bulldogs, Bull Terriers, Fox Terriers,

Labrador Retrievers, Dachshunds and Weimaraners than in other

breeds.  Most dogs are middle-aged when affected.



Mast-cell tumors vary widely in shape and size, but they are

usually single tumors in dogs and multiple tumors in cats.  In

dogs, they occur most frequently on the trunk, limbs and anal

region.  Malignant growths in dogs are frequently located between

the toes.



                 Important Points in Treatment



1.  Mast-cell tumors should be surgically removed as soon as

    possible, since many are malignant.



2.  Irradiation and/or chemotherapy are recommended when

    mast-cell tumors are advanced or cannot be completely

    removed. Your doctor will advise you if your pet should

    receive this type of therapy.
