Note 52 — Chapter XLIV · THE BREAST.
Reading edition
It will be a safe rule to follow if it be assumed that every cyst whose contents are bloody, unless this can be traced to recent accident, and especially every cyst whose interior is papillomatous, is on the border-land of malignancy, if not malignant in character. All such tumors then should be extirpated. If they occur in the breast a complete operation, as for cancer, should be done.
