The microscopists, whose lively imaginations make them see things that do not exist, would make us believe that they can take a small section of the suspected growth, and establish the existence of cancer by microscopical examination; this is utterly impossible, because the cancer cell is no different from normal cells, and in erosions we often find the follicles so close to each other, and their cells so closely packed, one on the other, that no candid mind can say whether it is a malignant or an innocent growth. The claim that “nests of epithelium cells,” as the stereotyped phrase goes, constitute scientific evidence of cancer, is utterly absurd. Such eminent authority as Professor Arnold, of Heidelberg, makes the assertion that positive diagnosis of cancer, from a small section or scraping, is impossible. I am myself fully convinced of the truth of this assertion, for while I was making microscopical studies in Germany, I had abundant evidence of the truth of this statement. It is indeed very unfortunate, both for science and suffering humanity, that as yet there is no absolute means of diagnosing cancer positively, and for that reason the quacks, and those who are not quacks, will continue to fleece their victims for supposed cancer. I believe that the cause of cancer is either due to a _ptomaine_ or organic poison that is generated in the body, or to a specific germ or bacillus. If it be due to the latter, and the germ theory of disease makes that highly probable, there is no doubt that a method of staining will soon be discovered, that will make the specific microbe recognizable in the field of the microscope, but as yet most cancer diagnoses by microscopy are only surmises. TREATMENT. Continence in sexual intercourse is one of the prerequisites to the successful treatment of all uterine diseases. This is so often overlooked by those giving advice in such matters, that their otherwise appropriate suggestions for treatment are frustrated. The women who are suffering, appreciate the value of this interdiction without further argument, but the average man does not appear to have the common sense to readily comprehend that the mechanical irritation incident to the sexual act, and the accompanying physiological congestion, will surely aggravate an inflammatory process, no matter of what nature. Men, whose animal instincts dominate their entire being, so that reason, if they ever had any, is dethroned, should stop to consider their immoderate conduct, which perpetuates the suffering of their wives from ailments which men themselves have often inflicted, and for which women are innocent martyrs. The acute variety of uterine catarrh is to be treated like all other acute inflammatory diseases. The patient should at once take to bed, so that she may keep herself warm and quiet.
