Which type of skin tumor is the most common in cats?

Squamous cell carcinoma is recognized as the most common type of skin tumor in cats. This type of cancer arises from the squamous cells, which are flat cells that make up the outer layer of the skin. One of the notable factors contributing to the prevalence of squamous cell carcinoma in cats is their susceptibility to sun-induced damage, particularly in areas of the skin that are not heavily pigmented, such as the ears and nose.

Cats that are outdoor or have limited shade exposure are at a higher risk, as ultraviolet light can induce mutations in the squamous cells, leading to malignancy. Additionally, squamous cell carcinoma in cats can present in various forms, including superficial and invasive types, which may influence its detection and diagnosis rates.

Understanding the epidemiology of skin tumors in felines is crucial for effective prevention, early detection, and treatment, emphasizing the need for regular veterinary check-ups in cats, especially those at greater risk. This awareness allows pet owners to recognize the potential signs and symptoms of skin tumors, fostering timely intervention and improved outcomes.
