Feline Mast Cell Tumors
Jul 26, 2018
Mast cells are a type of normal white blood cell and are part of the immune system. Mast cell tumors (MCT) comprise about 20% of all cutaneous (skin) tumors in the cat. These tumors can be benign (not cancerous) or malignant (cancerous and able to spread to other parts of the body). Over 90% of MCTs that occur in the skin of cats are benign while visceral (occurring in internal organs) MCTs may behave more aggressively. This disease is seen mostly in middle-aged cats, and Siamese cats appear to be predisposed to getting this disease.
