Breast Cancer is the single most common cancer, and the third leading cause of cancer cancer deaths, in the United Kingdom. Breast screening is able to detect breast cancer in the early stages of development, during which time it is more easily treatable. Unfortunately, many patients do not attend screening, and surveys issued to these women consistently report "forgetfulness" as the primary reason for missing the appointment. Both telephone reminders and postal reminders have been shown to reduce non-attendance, however, these are time consuming and expensive.
