Definition of Carcinoma
Epithelial cells form the surface layer of tissue throughout the body: the skin, mucous membranes, and serous membranes (lining of the internal body cavities). This tumor is the most common form of cancer.
Tumor generally carries the name of the tissue or site of its origin; for example, basal cell carcinoma originates in the basal cells of the skin and adenocarcinoma originates in a glandular structure.
