Case Discussion

This patient was religiously conscientious in her annual mammograms. On initial screening, the mammogram was normal. The carcinoma developed in 12 months and even with the wisdom of hindsight the lesion is not visible a year before. This is an example of the development of an interval carcinoma of the breast.
