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,…).

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%.
