Tongue Cancer (Squamous Cell Carcinoma) in Dogs

A squamous cell carcinoma (SCC) can be described as a malignant and particularly invasive tumor that takes hold in the scale like cells of the epithelium – the tissue that covers the body or lines the cavities of the body. These scale like tissue cells are called the squamous. Carcinoma is, by definition, an especially malignant and persistent form of cancer, often returning after is has been excised from the body and metastasizing to other organs and locations on the body.

Dogs can be afflicted with several types of tumors, including in the mouth. Squamous cell carcinomas on the tongue are usually located underneath the tongue, where they attache to the bottom of the mouth. They can be white in color and sometimes have a cauliflower shape. This type of tumor grows and metastasizes quickly to other parts of the body.

As with many types of carcinomas, this is usually seen in older dogs. In this case, older than seven years of age.
