SCC
Issue Description
Squamous cells are the cells that make up most of the skin, so squamous cell carcinoma refers to an abnormal growth of these cells. Squamous cell carcinoma is
usually developed in the epithelial layer of the skin and sometimes in various mucous membranes of the body. This type of cancer can be seen on the skin, lips,
inside the mouth, throat or esophagus. This type of cancer is characterized by red, scaly skin that becomes an open sore.

Symptoms
Squamous cell carcinomas commonly arise in non-pigmented, either sparsely-haired or un-haired skin. It is most commonly seen as a result of sun damage.
The lesion looks like a raw ulcer or non-healing sore. This dog skin cancer is locally aggressive but rarely spreads until later in the course of the disease.
Diagnosis
To be diagnosed, a biopsy is done where a sample is taken and examined under a microscope.
Treatment
Surgical removal is the treatment of choice. Where surgery is incomplete or not possible, radiation can be used. Limiting exposure to the sun may help prevent
sun-induced squamous cell carcinomas.
