In a recent and interesting discussion1 of preventive medicine occurs the statement:
Prompt and aggressive treatment—a purely curative process— takes on a strongly preventive coloring because it may forestall serious deterioration or death. This is true also of cancer, a nonpreventable disease of unknown cause which can nevertheless be cured in many instances by surgical removal or radiological destruction of the lesion.
