Excerpt: ...are found in the mammary glands and the uterus; so when you exclude carcinoma of the mammary gland and of the uterus, the death-rate is reduced very materially. There have been at different times great disputes as to the particular cancer-cell that is to be found in each special variety of carcinoma. There is no longer belief in any specific cancercell; that is to say, the cancer is now believed to be a growth of epithelial tissue which has grown out of place. You will not be far wrong if you view all carcinomata as one disease, the alleged subdivisions as many of them arbitrary, and all of them founded on clinical differences, some of which may be accidental. Hamilton's (of Aberdeen) definition of cancer is "a neoplasm formed of any tissue whose fibrous interspaces and lymphatic vessels are infiltrated with actively proliferating epithelial cells." Carcinoma may be developed in any part which has epithelial tissues, or any organ of Fig. 14.--Stratified-cell Carcinoma. Obj. No. 3. a, a. Rows of carcinoma cells, b. Carcinoma pearl, c, o.

Artery. the body which has epithelial tissue in its substance. Now, we distinguish carcinomata in general from other tumors of the body by what we term the alveolar structure, wherein the so-called cavity or cell is formed. I show you here a diagram from Cornil and Ranvier, which exhibits this alveolar structure very clearly. We find that these alveolar spaces are filled with epithelial cell infiltrations. I say infiltrated, because they are not naturally there; they do not belong to the part. All these cells have...
