DUNCAN BULKLEY, A.M., M.D. Senior Physician The New York Skin and Cancer Hospital, etc. [Illustration] NEW YORK PAUL B. HOEBER 1915 Copyright, 1915 BY PAUL B. HOEBER _Published, February, 1915_ Printed in U. S. A. To THE GOVERNORS of the NEW YORK SKIN AND CANCER HOSPITAL whose kind appreciation of and assistance to the author in his clinical work in their institution have done much to encourage him and to promote the interest of the profession in the branch of DERMATOLOGY this little book is inscribed PREFACE 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 derangement in the vital forces of the organism, as influenced largely by diet and mode of life. It has, therefore, seemed to the writer that it was time to stop and look at cancer from a broader aspect, and by synthesis and deduction to seek to understand some of the underlying causes of malignant disease; also to see if some general principles could not be ascertained upon which could be based an explanation of the views he had long held, and of the practice which he had long followed in regard to the prevention and cure of this dire malady. And as his studies progressed he was more and more satisfied that the true solution of the cancer problem lay along the lines indicated, although there was still very much to be learned regarding the details and application of the principles involved.
