الصفحة 334 - The phagocytosis of formed cellular elements plays an important role in inducing resistance ; serum is impotent to produce resistance, blood corpuscles do so. The energetic phagocytosis which accompanies the spontaneous absorption of transplanted tumours, and which occurs in absorption after exposure to radium, speaks strongly for the conclusion that the processes are the same in kind when blood or tumour cells, being absorbed, produce resistance. But we are as yet unable to determine the extent...
الصفحة 22 - ... cancer, its apparent greater frequency in some geographical areas (whether large or small) than others, the presumable importance of race, diet, soil, climate, are all problems of much less importance than the infective or non-infective nature of cancer ; but we must not lose sight of the fact that it is in all probability as much without the province of statistics to supply the direct answer to the question, What is the cause of cancer ? as it was for statistics to directly prove the causes...
الصفحة 312 - A study of the influence exerted by a variety of physical and chemical forces on the virulence of carcinoma in mice. By GHA Clowes, Ph.D. Evidences that infected cages are the source of spontaneous cancer developing among small caged animals.
الصفحة 3 - I cannot refrain from pointing out that the number of deaths assigned to cancer increases from one country to another in a manner parallel with the increasing accuracy of the vital statistics of the several countries.
الصفحة 21 - ... must remain indispensable so long as we are unable to test the relative importance of each. The relative importance of some of these circumstances can only be finally cleared up after the true nature of cancer has been ascertained, and the purely statistical investigation of the incidence of cancer will remain more or less empirical until this end is attained. The statistical investigation of infective diseases was pursued empirically before the developments of bacteriology directly demonstrated...
الصفحة 21 - ... statisticians make of the available data. Until we shall be able to start cancerous proliferation in a tissue at will, we shall remain in this same unfavourable position for determining the true importance of many circumstances, which at the same time it is unjustifiable to ignore. The increased number of deaths recorded from cancer, its apparent greater frequency in some geographical areas (whether large or small) than others, the presumable importance of race, diet, soil, climate, are all problems...
الصفحة 5 - ... whooping-cough and suicide." In briefly summarising the impression made by a study of the death-rates from cancer in European countries, I may state that comparisons between different countries, with a view to establishing differences in the absolute incidence of cancer, appear to me to be entirely fallacious. The dimensions of the differences are not so great that they are incapable of explanation by (1) the varying difficulties in the way of obtaining accurate records of the numbers of deaths...
الصفحة 5 - ... statistics, new growths are grouped together, in a more indiscriminate fashion, eg, in Switzerland, for males, all fatal diseases of the prostate gland are grouped under the heading of " cancer " of that organ. The factor introducing most disturbance into the number and the value of the data is probably the manner in which the certification of deaths is effected, and the extent to which this is solely the duty of medical men, as in some States, or merely the ignorant opinion of a layman, after...
