The first case showing the effect of dietetic and other non-surgical treatment to which I would call your attention is the private patient who so kindly exhibited herself, veiled, at our lecture week before last. I showed it then purposely as a case undergoing treatment, now for eight months, in which there was still evidence enough of the disease, with the history presented, for those who examined it to confirm the diagnosis of unquestionable cancer. _Case I._—Miss T. M. M., aged 37, consulted me on March 23rd of this year, for a mass in the left breast which a surgeon of great eminence had diagnosed as cancer, and urged most strenuously an immediate operation, and from its rapid development had said that she would die within six months if not operated on. She had had a neurasthenic breakdown the preceding autumn, and for some months had now been under a very great nervous strain, with a father aged 71, who was slowly dying of Bright’s disease. Two years ago she had suffered severely from uricacidemia, for which she had dieted six months. The mass in the left breast was noticed only a month or two previous to her visit and had increased rapidly; when seen there was a hard, lobulated mass about two inches in diameter, in the outer, upper quadrant of the left breast, attached to the puckered skin over an area of more than an inch; there were also a number of enlarged, hard axillary glands. There was considerable pain at times, which had been increased considerably by the rather rough handling of the surgeon. She was placed on an absolutely vegetarian diet, following what I call the green card menu, which I gave you in my last lecture, and a mixture of acetate of potassium, nux vomica, fluid extract of cascara and fluid extract of rumex root, which I also mentioned to you at that time. For eight months she has been under my constant observation every week or two, and the improvement in her general condition and in the breast tumor is very marked; you heard her say that she felt a thousand per cent better. Her color is excellent, she has held her weight, 153 pounds, which is a trifle above that called for by her height and age, and all this in spite of daily office work and very great trouble and anxiety in nursing her sick father for thirteen weeks, who died in October. The breast, as you see, has still a lump in it, but it is soft and hardly half the original size, the area where the skin was attached has decreased, so that there is now only this slight dimpling or puckering, and the enlarged lymphatic glands in the axilla have disappeared.
