Carcinoma

Carcinoma is a malignant tumor arising from epithelium (lining and covering a number of organs: the mucous membranes of the digestive, respiratory, urinary and genital systems, skin, glands,…).
 * Carcinoma arising from glandular epithelium = adenocarcinoma.

According to the consistency, the ratio of tumor tissue (parenchyma) to connective tissue content, carcinomas are divided into:
 * Soft (medullary): tumor parenchyma is represented here by more than 50%; it is often dependent on the diagnostics only;
 * Medium stiff (carcinoma simplex): the ratio of parenchyma to the connective tissue is approximately the same;
 * Hard (scirrhus): the proportion of connective tissue is more than 50%.
