Looked at from its broadest aspect, in connection with what I have tried to show here and on former occasions, all cancer will be inoperable, or rather, not needing operations, when the principles I have tried to develop are fully elaborated by the wide experience of others, and when they are firmly established, and correctly carried out. For when it is universally realized that it is the errors of life, determined and accentuated by advanced civilization, so-called, which lead up to and cause cancer, and when public education has been advanced along correct lines, the tendency to cancer will diminish and there will be fewer cases, either operable or inoperable. The former will melt away under correct internal and external measures, and the latter will be helped by, or slowly yield to the same, unless the malignant process has already progressed beyond the possibility of retrogressive metabolism. But, of course, it is too much to expect that such longed for results will be fully attained within a generation or two. INOPERABLE CANCER is truly a most distressing condition, especially after it has become so after one or more surgical operations. The hopelessness and despair of the patient when told that no operation is possible is bad enough. But when with recurrence, time and again after repeated operations, it is decided that no further relief by the knife is possible, the despondency is indeed pitiful—especially as ordinarily one can only look forward to a sure and most painful death, at a not very distant day. It is very difficult to convince many of these patients that medical treatment, including diet, can do any good, so firmly fixed is the idea that an operation is the only possible remedy; many, therefore, get weary of the restraint necessary when immediate results are not seen. And yet in my previous lectures I gave several such cases to show that much can be done medically along these lines, even in these distressing cases, and later shall hope to narrate other instances, similar to those reported in my lectures two years ago.
