Carcinoma is a malignancy that develops from epithelial cells.^[1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal^[2] or ectodermal germ layer during embryogenesis.^[3]

Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and becomes malignant. It is from the Greek: καρκίνωμα, romanized: karkinoma, lit. 'sore, ulcer, cancer' (itself derived from karkinos meaning crab).^[4]
