Squamous Cell Carcinoma (SCC) is a type of malignant tumor that arises from the squamous epithelial cells. These cells are flat, scale-like cells that make up the outermost layer of the epithelium. SCC can occur on various parts of the body, including the skin, lungs, and esophagus. It is most commonly found in areas exposed to ultraviolet (UV) radiation, such as the face, neck, and hands.
