Thus in the effort to get at and remove all possible or prospective cancerous lesions, many innocent or non-malignant adenomata, etc., are operated on, which are afterwards found to be such microscopically. In the same way it is quite possible that some of the small breast tumors which have disappeared under the dietetic and medical measures here described were still non-malignant, and should not be grouped with carcinoma. It is fair to say, therefore, that among my notes are also 22 cases of breast tumors which have been excluded from the carcinoma list, and entered with other titles, such as abscess, cyst, chronic mastitis, adenoma, etc. But I claim that even if some of these also disappear under the measures we are considering, as they frequently have done, it is a better and more desirable result than if they had been removed by the knife: for in the former case the cause which induced the unnatural growth has been overcome, whereas by surgery only the obnoxious mass has been dislodged, and perhaps with it adjoining tissue and glands, but nothing has been accomplished toward checking the cause producing the offending lesion. But the very fact of the frequent recurrences after operation, in the neighboring skin or elsewhere, demonstrates the fact that surgery is but an attempt to rectify past errors, which might or might not have been prevented by careful medical foresight and action; we must, however, be thankful for the measure of success which has followed the noble efforts of our distinguished surgeons, only it is to be hoped that hereafter other measures will also be more commonly adopted, looking towards a prevention of the recurrence of carcinoma after operation. Not to detain you too long with these clinical considerations, I would like to give the details of a few of the cases which have been most striking.
