Squamous cell carcinoma (SCC) is a tumor of the cells that make up the contact or upper layer of the skin. UV light exposure has been described as a developmental factor in people and appears to be associated with its development in cats. Areas affected include the ear tips, skin, toes, or peri-ocular region. Fine needle aspiration or biopsy may be performed for diagnosis. The metastatic rate does not appear overly clear, though staging is always recommended. SCC of the toe can occur as a primary tumor or may have spread from the lung (lung-digit syndrome). Surgery is almost always recommended in any case of SCC; the role of chemotherapy is controversial. Radiation therapy has an excellent response rate in cats with the SCC affecting the nasal planum and may give long-term tumor control.

Tumors of the epithelial, glandular stomach lining include non-cancerous polyps and some types of chronic (hyperplastic) gastritis. Malignant epithelial tumors (gastric adenocarcinomas) cause progressive illness.

Skin gland, hair follicle, and sebaceous gland tumors are often benign. Matrical carcinoma and sebaceous gland adenocarcinoma are rare and more aggressive forms of the disease. Regardless of the type (sweat, hair, or sebaceous) diagnosis is made by fine needle aspiration, biopsy, and/or surgical removal and histopathology. Further treatment is reviewed.

The thyroid gland is a two-lobed endocrine gland wrapped partially around the front of the trachea (windpipe) just below the throat. Its function is the production and release of thyroid hormones.

These are tumors of the blood vessels of internal organs. Some are benign (hemangioma) but most are malignant (hemangiosarcoma).

Cancer is the result of genetic damage to cells. While some breeds may be more predisposed to certain forms of cancer, age-related changes and environmental factors are also often at fault. Some tests can be performed to determine the type of cancer present. Treatment options are available but do not necessarily cure cancer.

Regular preventive health care for your cat can increase the length and quality of her life. Healthcare guidelines are established and kept up to date using the most recent evidence-based recommendations including the recommendation that all cats receive a complete veterinary examination at least once a year or more frequently, depending on their individual needs and health concerns.
