A carcinoma , Latin carcinoma , also Carcinom [ kartsiˈnoːm ] (from the Greek καρκίνος karkínos , "cancer", and karkínoma , "cancerous disease"), abbreviated Ca , is a cancer that starts from cells in the covering tissue of the skin or mucous membrane ( epithelium ) . More precisely, it is an ectodermal or entodermal neoplasm; this results in a further differentiation depending on the type of degenerated epithelium. Most carcinomas arise from the squamous epithelium (Squamous cell carcinoma or squamous carcinoma) or from the glandular epithelium ( adenocarcinoma ). Primary lymphogenic metastasis is particularly common in carcinomas.

Carcinomas make up around 80% of all malignant tumors . The stage is described with the TNM classification . Surgical removal, radiation and chemotherapy, and in the very early stages superficial ablation can be used as therapy. The alternative medical spelling is carcinoma .
