While it would be absurd to say that hypnotism can cure tuberculosis or cancer, it is fully justifiable to say that hypnotic treatment in tuberculosis or cancer is to a high degree beneficial, inasmuch as it can secure sleep, appetite, and freedom from pain, three factors which indirectly help to fight the disease. The elimination of pain may sometimes also play its role in slight operations where other methods of narcosis seem for any reason undesirable, and very frequently hypnotic suggestion has been used for this purpose at childbirth. The same importance which belongs to the removal of bodily pain in the treatment of a peripheral disease may be given to its mental counterpart, to the worry, excitement, and emotional shock. They all stand in the way of a real success in any cure. Even the chances of a dangerous operation are entirely different for the patient who goes to it with free mind and a happy mood, with full confidence in its success, from those of a patient who has worked himself into a state of fear and anxiety. Here again the depression and the excitement are not in question as symptoms of a disease, as they were when we discussed the phobias and despondencies of the neurasthenic and of the hysteric. They are merely normal side-effects of the bodily disease, accentuated perhaps by a suggestible temperament. To eliminate all these emotions means to change most helpfully the whole atmosphere of the sick-room and to deprive invalidism of its saddest feature. This negative factor corresponds of course most directly to the positive feature of building up new hope and joyful expectation. He who creates confidence makes convalescence rapid and strengthens the power to overcome disease.
