A squamous cell carcinoma of the tonsils is an aggressive and metastatic tumor that arises from the epithelial cells of the tonsils. The epithelium is the cellular covering of all of the internal and external surfaces of the body. While all types of squamous cell carcinomas are invasive, carcinoma of the tonsils is particularly aggressive.
This type of tumor is highly invasive, fast progressing and spreading. This tumor also metastasizes to other areas of the body.
As with other types of squamous cell carcinomas, middle-aged and older dogs are more commonly affected. In this case, the incidence is higher in dogs living in urban areas as compared to those in rural environments.
Common systems of squamous cell carcinoma of tonsils are as follows:
Difficulty with eating
Difficulty swallowing (dysphagia)
Bad breath (halitosis)
Oral discharge with blood
