Improving Breast Cancer Screening Uptake Through Tailored Reminder Letters

Belgium7,947 participantsStarted 2024-04-01

Plain-language summary

The goal of this trial is to learn whether a culturally and linguistically tailored reminder letter can increase participation in the Flemish Breast Cancer Screening Program among women who previously did not attend screening. The study also examines whether the effect differs between socioeconomic groups. The main questions it aims to answer are: * Does a tailored reminder letter increase participation among previous non-attenders? * Does the effect differ between women with lower and higher socioeconomic status? Researchers compare two groups: * Intervention group: receive the standard invitation letter plus an additional tailored reminder letter. * Control group: receive the standard invitation letter only. Participation in screening within 40 days of the invitation is measured using the program's registry. Participants are women aged 50-69 years who had previously been invited but had never attended screening. The reminder letter is sent as part of routine screening communication, and no additional medical procedures are involved.
