When seen the whole breast was involved, was double the size of the other, hard, immovable, and with an adherent crust over an ulcerating surface on its lower half, several inches in diameter, from beneath which was a moderate discharge: the axillary glands were enormously enlarged, as also the supra-clavicular, and she was strongly cachectic. She was placed on an absolute vegetarian diet, with no coffee or tea, and appropriate medical treatment, and the breast kept painted with fifty per cent. ichthyol and water, care being taken not to disturb the adherent crust. In a very short time the discharge ceased, and the protective crust adhered until her death from exhaustion, with pulmonary œdema, on September 9th, 1914. On August 15th it was recorded that the breast had done very well, that it was soft and movable, and not larger than the other breast, with no discharge, and no pain since a short time after beginning treatment: the axillary glands had diminished three-quarters in size, and the supra-clavicular glands were also very much smaller. And now, gentlemen, my task is done. I have tried to let you see cancer through my spectacles, as I have seen it for very many years past, and to share with me my optimism in regard to the prophylaxis and cure of cancer, if only there can be sufficient enlightenment in the profession and public: and I must tell you that in collating and preparing the material to support my long held views I have expended very much more time and labor in study, for some months past, than I could have believed possible. But as the subject developed, and as I discovered more and more support for my thesis, there was a fascination about the work which I could not resist; and if I have tried you with the many details of proof presented I beg that you will pardon me: for I wanted to present the subject so strongly that my hearers, at least, would accept the propositions I have developed, and believe what I have said in regard to my own experience with the terrible disease under consideration, and act upon both, and thus aid some sufferers with cancer. From my recent article on “The Relation of Diet to Cancer” many medical journals have quoted me as ascribing the disease wholly to the use of meat, but you who have heard these lectures now know that animal proteids are only one of the contributing causes.
