Mast Cell Tumours in Dogs

Individual or multiple masses on or just below the skin. Varied appearance, ranging from raised nodules to swollen, ulcerated masses. Size can vary, with some as large as 20-30cm. Inflammation and swelling of the skin around the tumour. Systemic effects like loss of appetite, vomiting, weight loss, and more.

If you notice suspicious lumps or symptoms, consult your vet. Diagnosis methods may include routine blood tests, fine needle aspirate (FNA), biopsy, ultrasound, and X-rays to determine the extent of the tumour.

Surgical removal is the preferred treatment. Complete removal with appropriate margins can result in a cure. Analysis of the removed mass confirms the absence of cancer cells. Radiotherapy and chemotherapy may be considered based on the extent of the disease.

Prognosis varies based on factors like tumour grade and stage. Early detection and treatment improve life expectancy. Low-grade MCTs can be cured with proper removal, while high-grade MCTs may have a more guarded prognosis, with chemotherapy potentially extending life expectancy.

Dogs with MCTs, even if cured, should be regularly monitored for new skin lesions throughout their lives, as new tumours may develop. Understanding and addressing mast cell tumours early can significantly impact your dog’s health and well-being. If you suspect any issues, consult your vet promptly for guidance.
