🔬 Additional Cancer Facts for Cats
- White and light-colored cats are especially prone to sun-induced squamous cell carcinoma on the ears, eyelids, and nose — keeping them indoors or limiting sun exposure helps reduce risk.
- Mammary tumors are the third most common cancer in cats, and over 85–90% are malignant. Spaying before the first heat cycle can reduce the risk by up to 90%.
- Lymphoma is the most common cancer in cats, and there’s a strong link between feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infection and lymphoma development.
- Secondhand smoke exposure in cats is linked to a higher risk of oral squamous cell carcinoma and lymphoma. Cats groom themselves, which means smoke particles settle on their fur and are ingested.
- Obesity not only increases the risk for diabetes and arthritis but is also a known cancer risk factor in both cats and humans.
