Cancerous basal cell tumors are the most common skin cancer in cats. Middle-aged cats are most susceptible to these tumors along with Persians and other long-haired breeds.

Common Types of Neoplasia in Pets Skin - Skin neoplasia is very common in older dogs, but much less common in cats. Most skin neoplasms in cats are malignant, but in dogs they are often benign. Your veterinarian should examine all skin neoplasms in a dog or cat to determine if any are malignant. Mammary Gland (Breast) - 50% of all breast neoplasms in dogs and greater than 85% of all breast neoplasms in cats are malignant. Spaying your female pet before 12 months of age will greatly reduce the risk of mammary gland neoplasia. Head & Neck - Neoplasia of the mouth is common in dogs and less common in cats. Signs to watch for are a mass or tumor on the gums, bleeding, odor, or difficulty eating.
