. The breast: its anomalies, its diseases, and their treatment . ional changes occur in the breasts of young patients suffering from such chronicinfectious diseases as tuberculosis and (according to published statements) actinomy-cosis, as well as in cases of squamous-cell carcinoma which cannot possibly arise from of these considerations taken together make too ready an acceptance of thedoctrine that abnormal involution is the precancerous stage of cancer a of the abnormal involution being the cause of the cancer, may not cancer bethe cause of the abnormal involution? Granting that abnormal involution is a dis-turbance of growth in the epithelial tissues of the breast, provoked by general or localstimuli, may not the presence of the cancer, like that of tuberculosis in the breast, bethe local stimulus that leads to the abnormal involution? May it not be worse incancer cases because there is a greater disturbance in such cases? May it not be mostmarked near the cancer because the greatest local disturbance is near the cancer?.

Finally, may not the differences that obtain between the appearance and arrangementof the cells of the abnormal involution lesions and the cells of the cancerous lesions de-pend upon the fact that they are not the same things and therefore ought to lookdifferent? It is sometimes urged that both the conditions, cancer and abnormal involution,are most frequent at the same period of life, and that therefore they are probably con-nected with one another. We cannot see the necessity for supposing that two condi-tions that happen to coexist must be connected with one another in the relation ofcause and effect. At a certain age the breast is subject to involution which sometimesbecomes abnormal and peculiar, at the same age cancer develops in the breast, irre-spective of any cause or condition known, but the involutional changes are a
