Squamous cell carcinoma specifically affects epithelial tissue, which is the layer of cells that lines both the internal and external surfaces of the body. Epithelial tissue is composed of closely packed cells, and it plays essential roles in protection, absorption, secretion, and sensation. Squamous cell carcinoma arises from squamous cells, which are flat, scale-like cells found in the skin and lining of various organs, including the respiratory and digestive tracts. This type of cancer is often associated with prolonged exposure to ultraviolet (UV) radiation or other damaging agents.

The other types of tissue, such as nervous, muscle, and connective tissue, do not develop squamous cell carcinoma because each type has distinct cell structures and functions. Nervous tissue is responsible for transmitting signals in the body, muscle tissue facilitates movement, and connective tissue supports and binds other tissues together. Additionally, these tissues have different cellular compositions, making them less susceptible to the specific changes that lead to the development of squamous cell carcinoma.
