It is impossible in a single lecture to tell you of all the indications and teachings which may be learned from the urine, much of which must be acquired by close observation and experience. The urea is almost always diminished, and this indicates an imperfect anabolism of the body cells, as the urea represents the final metabolism of their nitrogen. Uratic deposits are not uncommon, but other evidences of faulty nitrogenous metabolism also occur, free uric acid, ammonia, aromatic oxyacids, etc., whose individual significance in relation to cancer it is hard to trace, but clinically these derangements seem to have to do with the virulence of the disease. Indican in excess, and often greatly increased sulphates, are common, evidencing disturbed intestinal action. All these and other abnormalities, having to do with a deranged blood current, are to be rectified by proper treatment, the minor details of which cannot be elaborated in a single lecture. I have told you that imperfect intestinal excretion and constipation are almost invariably found in the subjects of cancer, even in very early stages and long before they have been induced by opiates given for pain. I may here remark casually that even in severe inoperable cases up to a fatal ending, I seldom have to give morphin when the patients are under a full and complete line of dietary and other proper treatment; these latter seem to so change the character of the blood stream, or act in some way so that there is not the pain previously suffered. Possibly it is in part through lowering the blood pressure. The subject of intestinal stasis or constipation is, with urinary derangement, such a very large one that it cannot be fully compassed in a single lecture. So I shall take the liberty of speaking dogmatically and shall tell you more or less definitely what observation and experience has taught me to do along these lines of faulty urinary and intestinal action in cancer. And really you will find it similar in many respects to the lines of theory and practise which I try to develop for you in connection with certain diseases of the skin. For, after all, in many conditions of disease we are to treat the patient in regard to a disordered system, and not always so much the particular disease by name. You will also remember that I have told you how it was by observing certain breast tumors which had been diagnosed as cancer by competent surgeons, urging immediate removal, disappear without operation under such treatment as I was giving for other complaints, that led me to my present point of view and practise.
