Where does squamous cell carcinoma occurs in what layer of the skin?

Squamous cell carcinoma (SCC) is a type of skin cancer that occurs in the squamous cells, which are thin, flat cells that form the outermost layer of the skin (the epidermis). SCC typically develops in areas of the skin that have been exposed to excessive ultraviolet (UV) radiation, such as the face, neck, hands, arms, and legs.
