Another fact, attainable only by the study of English statistics, is the singular regularity with which malignant disease selects different parts of the body year after year. If proclivity to this mysterious ailment were a matter of chance, or dependent upon the irregular action of certain forces, we should certainly fail to find such uniformity, or such approach to uniformity, as exists. One year, for instance, there would be, let us say, a preponderance of attacks upon the skin; another year the digestive organs would be the principal sufferers; a third year the joints and muscles would be chiefly involved. The actual experience proves that we are subject here to forces of incalculable stress, which nevertheless press steadily and uniformly upon humanity, where the habits and environment are the same. In the year 1901, for example, of the total number of fatal cases among men, the seat of the disease was the stomach in a little over 21 per cent. of the total number of cases. In 1910 the proportion was also 21 per cent. During the ten years 1901-1910, of the total mortality, the stomach was the organ involved in but a fraction over 21 PER CENT. OF THE TOTAL CASES. Is cancer increasing? This is a question of vast importance to the human race. That in proportion to total population more die from the disease to-day than twenty or thrity years ago, is a fact about which there can be no doubt. Dr. Stevenson, in the Report of the Registrar- General for the year 1910, tells us that in "all countries from which returns have been received the mortality has shown a general tendency to increase in recent years." Speaking on the "Menace of Cancer," the statistician of the Prudential Insurance Company of America affirmed that "the cancer death-rate in the United States is increasing at the rate of 2.5 per cent. per annum, and a corresponding increase is taking place practically throughout the civilized world." The cancer- rate among men in the United States has increased, according to the same authority, 29 per cent. during the last decade. The steady increase of cancer year after year is strikingly shown by a curve diagram, based upon the English mortality for several years.
