The Treatment of Bladder Growths.

Age and Nature of Growth. Although the pathology of bladder growths is. a complicated subject it may be said that there exists a complete gradation from the perfectly innocent single pedunculated papilloma to the very malignant infiltrating carcinoma. In between these two extremes we have growths which are difficult to place either amongst the benign or amongst the malignant, not only' clinically but even when we have obtained specimens so that the pathologist may examine them microscopically. Another fact that we must bear in mind is that in elderly patients showing a tendency to form new growths in their bladders,. it is only too likely that the type of neoplasm will change in the course of years. Whereas at first they come up to us with a pedunculated papilloma, later they return with recurrences that approximate nearer and nearer to the infiltrating carcinoma.
