Dog Mast Cell Tumour Recognition and Management

Mast cell tumours are the most common skin cancer in dogs, with welfare implications ranging from local discomfort to life-threatening systemic disease depending on grade.

Key Facts

Mast cell tumours account for approximately 20% of all canine skin tumours
Boxers, Labradors, and Golden Retrievers have elevated breed predisposition
Tumour grade determines prognosis with Grade 1 tumours having excellent outcomes after surgery
Mast cell degranulation releases histamine causing systemic effects including gastric ulceration
Targeted tyrosine kinase inhibitors have transformed treatment of high-grade tumours

Welfare Considerations

Mast cell tumours cause local discomfort, potential ulceration, and systemic effects from histamine release. Early detection and appropriate management can dramatically improve welfare outcomes, making skin monitoring and prompt veterinary assessment important for at-risk breeds.

What You Can Do

Check your dog's skin regularly for new lumps and have any growth assessed promptly
Be aware of breed predispositions to mast cell tumours in your dog
Advocate for pet insurance that covers cancer treatment to enable welfare-appropriate care
