Cancer is due toproliferation of the epithelium of the acini (acinous cancer) or of the ducts(duct cancer). Acinous cancer is vastly more common than duct cancer. Usually thereis much connective tissue and but little parenchyma in the growth (scirrhouscancer). In some cases there is little connective tissue and much parenchyma(encephaloid or medullary cancer).

Usually thereis much connective tissue and but little parenchyma in the growth (scirrhouscancer). In some cases there is little connective tissue and much parenchyma(encephaloid or medullary cancer). If colloid degeneration of the parenchymaor stroma occurs, the growth is spoken of as colloid cancer. Scirrhus (Figs. 1085 and 1086), the common form of acinous cancer, is almostas hard as stone. On section it is concave, and Sutton says resembles anunripe pear. The tumor is without a capsule, and the epithelial cells aresurrounded by masses of fibrous tissue. Portions of tissue, even some distanceaway from the tumor proper, contain foci of proliferating embryonic epithelial.
