Cancer has hitherto been regarded almost wholly from its histological and surgical aspects. The investigators and practitioners along these lines have been innumerable, the work done prodigious, and the literature relating thereto enormous. But relatively little attention has been paid to the medical aspects of this most threatening malady, although voices have been raised from time to time, with more or less force, all joining in the same plea that the basic cause of the disease lies in some de

It may be safely said that no disease which has afflicted mankind has received as much attention as Cancer, or concerning which there has been as much diligent search to find out its nature and cause. Tuberculosis, which seemed at one time to threaten even the existence of the race, has sunk into relative significance, as we have learned its true nature and conquered some of the causes of its ravages, and reduced its mortality very largely. Syphilis, under various names, forms, and aspects, was

Cancer in man exists all over the globe, but in different degrees of frequency, according to varying conditions of life, as we shall presently see. Malignant growths occur also in animals and fishes, though also with greatly varying frequency under different conditions; but there are few real tumors in reptiles or amphibians. Tumors are also occasionally found in vegetable organisms, presenting increased growth and proliferation of cells, arising from adventitious, or abnormally evolving buds, a

In the first lecture we saw that cancer was an alteration of the normal cells of the body, whereby they take on a malignant action and continue to do so, destroying contiguous tissues and leading to a lowered vitality, with an apparent poisoning of the system, which finally causes death. As the cells of various organs furnish different secretions, which in health contribute to proper metabolism, resulting in growth or maintenance of the tissues, so these disordered cells are believed to secrete

In our earlier lectures we saw that cancer was undoubtedly a diseased action of originally normal tissue cells, due largely to perverted metabolism, the special features of which were brought out last week. In the second lecture we studied the frequency and geographical distribution of cancer, which was found to be very different for various peoples in diverse sections of the earth, and which we saw was proportioned in a great measure according to their diet and mode of life. In this lecture we

It is remarkable that so little serious attention has been paid to the medical treatment of cancer, in standard works, in view of the occasional strong statements and reports which have appeared from time to time in current literature and in occasional books, dating back for many years. Much of this, of course, relates to imperfect observation and erroneous diagnosis, and also to crude medical knowledge, but there have been also plenty of good men, who knew the disease and have reported favorabl

The test of everything lies in the results obtained. Theories, discussions, and arguments are all unavailing unless results show their truth. In medicine, however, it is sometimes difficult to demonstrate results until after the lapse of time, as was well illustrated by the preposterous claims first put forth for “606,” which is gradually attaining about its correct status. The same is true in regard to the surgery of carcinoma, where operations which formerly were attended with very bad results

Two years ago the present writer ventured to put forth a small book in which cancer was considered from quite a different standpoint from that commonly held by the profession and laity. The kindly reviews of the medical press indicated that, while this was antagonistic to accepted views, there was warrant for such an investigation, in view of the steadily increasing mortality from cancer all over the world, under the present mode of purely surgical treatment. In these two years there has been ve

In my lectures given here two years ago I considered, as far as I could in the time allowed, the nature of cancer, [1] and the evidence in favor of its being a medical rather than a purely surgical disease; and in order that the trend of what shall follow may be clearly understood, brief reference may be made to some of the principal points studied and developed in the preceding lectures. To this end I may restate the conclusions presented at their close, as developed in the lectures, perhaps wi

While cancer is no respecter of persons, and affects all, rich and poor, old and young, male and female, there are some interesting features regarding the disease as it occurs under various conditions which are worthy of consideration. We have seen in the former lecture that cancer is not a definite something, from without, that attacks the human frame, but that it is only a faulty development and action of certain body cells, which were once normal, with a steady decline in bodily health which

As has been already shown in these and previous lectures, the death rate from cancer has been steadily and alarmingly increasing in almost every locality, ever since statistics have been collected. The attempt has been made from time to time to show that this increase is not real, but is apparent, and that the error arises from three main causes. These are: 1. The increased longevity in general, leading to the existence of more people of the cancerous age; 2. Improved diagnosis; and 3. More care

We saw in our last lecture that surgery had failed to check the rising mortality of cancer, and that during the year 1915, in the United States Registration Area, the death rate had augmented from 79.4 to 81.1, or an increase of 1.7 persons in every 100,000 living; this was a greater increase than the average rise in the death rate for the preceding five years which was only 1.2 points. This, moreover, occurred during a still active period of laboratory research, with wide publicity as to cancer

1. Cancer is a serious disease which should receive constant medical care from the time it is first suspected. 2. “Cancer Specialists,” who advertise, should be avoided. 3. Cancer is not contagious, and there is no danger of communicating the disease to others. 4. Cancer is not a disgraceful disease, and there is no reason for being ashamed of it or hiding it. 5. As soon as cancer is suspected, whether there be a lump, or sore, or other symptoms, it should be at once cared for by a competent med

Two years have elapsed since I said to you in the last lecture of the former course, “The test of everything lies in the results obtained. Theories, discussions and arguments are all unavailing unless results show their truth.” I can now repeat the same phrases after two years’ further observation and experience. And I can also speak much more strongly than I did at that time, not only after testing the matters then presented further, in private and hospital practise, but also after an amount of

Cancer has long been a problem over which master minds have wrestled, and to read much that is written it would seem that we were yet as far from its solution as ever. Countless able men, at the expense of millions of dollars, have labored faithfully in the laboratory, and it may safely be said that more effort and time have been expended in investigations on cancer, and more has been written concerning it, than ever in connection with any other disease affecting humanity. And yet its mortality
