Dominant professional opinion tends to coincide with common sense in arguing that the earlier the patient gets to the therapist, the more likely is his life to be saved. Thus, for example, Wiggins et al '°' estimated that the overall five-year cancer survival rate of 25 percent in upstate New York could be doubled if all cases were treated early. In 1954, the medical and scientific director of the American Cancer Society, Charles Cameron, said that two out of every four people diagnosed with cancer in the next year could be saved by current methods of treatment. However, he went on to say that only one of those would be saved. The other would delay seeking help until his disease had progressed too far for him to be helped by even the most modern methods.&dquo;As a starting point in our review of the literature, we felt it important to subject this view to the test of evidence. MacDonald's 61 survey in 1951 of 236 articles that made more than passing reference to the significance of early treatment revealed that only 16 contained data that made it possible to correlate end results with early treatment. Moreover, in his opinion, most of these 16 &dquo;failed to establish any significant value for early treatment.&dquo; Most of the literature contained little more than stereotyped allusions to the desirability of early *This paper has been prepared in the course of a study on participation and nonparticipation in breast cancer detection examinations.
