Is Your Light-Colored Cat at Risk for Squamous Cell Carcinoma?
It’s July and the sun is shining! We all love soaking up the sun, but be careful with your light-colored cats! Nothing is more beautiful and regal than an all-white cat with piercing green or blue eyes, but these and other light-colored kitties are at a higher risk for developing squamous cell carcinoma, a common cancer of the skin and mouth.
What are squamous cell carcinoma signs in cats?
Squamous cell carcinomas initially appear as small sores that do not heal. As they grow, they often become raised, irregular lumps that may or may not have open sores. A single tumor is most common, but multiple tumors can develop, especially in sun-damaged areas.
Squamous cell carcinomas are usually highly invasive to the surrounding tissues and bones, and can metastasize to other body parts. Because they are so invasive, early detection is critical for a good prognosis.
What causes squamous cell carcinoma in cats?
Light-colored cats have less protection against harsh UV rays, and are most commonly affected with squamous cell carcinoma. White cats who sit in sunny window sills all day, with prolonged exposure to sunlight, are most at risk. The tumors often appear on areas where the cat’s fur offers little protection, such as the ears, eye ridges, eyelids, nose, and lips.
How is squamous cell carcinoma in cats treated?
Surgical removal of squamous cell carcinomas provides the best prognosis. However, other options, including topical creams that modify the immune system, laser therapy, cryotherapy, topical chemotherapy, and radiation treatment are available.
How can I prevent squamous cell carcinoma in my cat?
To reduce your white cat’s risk of developing squamous cell carcinoma, limit UV radiation. Use ultraviolet window screens, apply sunscreen, and keep your cat indoors during peak sunlight hours. Keep in mind that cats can be highly sensitive to the ingredients in human sunscreen products, so choose a formula that is labeled pet-safe.
