Not to go back too far, reference can be made to Lambe, who one hundred years ago wrote clearly in regard to the causation of cancer from luxurious living, and adduced strong proof to show the effect of diet in curing certain cases of undoubted cancer of the breast and uterus, the diagnosis of which was confirmed by prominent surgeons of the day, several of whom endorsed the vegetarian diet. Abernethy wrote pointedly, soon after, regarding the constitutional origin of tumors and says, “There can be no subject which I think more likely to interest the mind of the surgeon, than that of an endeavor to amend and alter the state of a cancerous constitution. The best timed and best conducted operation brings with it nothing but disgrace, if the diseased propensities of the constitution are active and powerful. It is after an operation that, in my opinion, we are most particularly incited to regulate the constitution, lest the disease should be revived or renewed by its disturbance.” He then gives an endorsement of Lambe’s dietetic treatment of cancer, and presents several reasons why it should be fairly tried. In the classical work of Walshe we find numerous references to the constitutional nature of cancer, original or quoted from recognized authorities, as well as expressions in regard to the futility of expecting that surgical interference would cure the real disease in any great proportion of cases. He says, “It would in theory appear that the removal of a tumor cannot in itself cure the disease, as the local formation is but a symptom of a general vice of the economy.”... “This tissue being, as the normal textures, the seat of nutrition, is like them susceptible of its disordered actions,” and he alludes more or less to the effect of diet on the disease.
