    the location of the disease. Carcinoma of the lip and of the pyloric orifice of the stomach are common in men, but rare in women, while, on the other hand, carcinoma of the breast and of the genitals are frequently seen in women and very seldom in men. Age.—Carcinomatous growths are most prevalent in persons who have reached or passed middle life. They are extremely rare in early life and very common in advanced age. Senile tissue changes seem to be particularly favorable to the development of the disease, while the consequent lowering of the powers of vital resistance and recuperation incident to advanced age places the tissues in a condition most favor- able for the rapid growth of a tumor-matrix and the dissemination of the carcinoma-cells through the system. Paget has published an interesting table showing the influence of age and the general increasing mortality of cancer with each suc- ceeding decade from birth to eighty years of age: facet's table. Under lO years 5 per cent. Between 10 and 20 years 6.g 20 ' ' 30 30 ' ' 40 40 • ' 50 so ' ' 60 60 ' ' 70 70 ' ' 80 100 113 107 126 Walshe has also shown from statistics that the death rate from cancer steadily increases with each decade until the eightieth year. When the disease occurs in young persons it is an evidence that the epithelial cells composing the tumor-matrix are unusually en- dowed with the power of cell-proliferation, or that the individual is peculiarly susceptible to cancer formation; or that the tissues contain- ing the misplaced epithelial cells have sustained an injury of some form which has lowered their vitality or physiologic resistance, and placed them in a condition to favor the growth and multiplication of carcinomatous cells.
