Mast cell tumors can develop in all ages and breeds of dogs. They are very rare in cats and humans. There appears to be a hereditary factor to these tumors as shown by some strong breed predilections. Dachshunds, English Bulldogs, Fox Terriers, and Staffordshire Terriers are all at increased risk. Boxers and Boston Terriers are at even higher risk and appear to have certain genes that make them more susceptible to the disease. One study has indicated that younger dogs that develop mast cell tumors are not as likely to develop the more severe forms of the cancer. The exact cause of mast cell tumors is still speculative. A viral source has been mentioned, as well as hereditary and environmental factors. It is quite possible that there are a variety of different causes for the development of this tumor. Because this tumor is not found in humans, there has not been as much research and information available for the veterinarian as there are for tumors that are found in both humans and anim
