The Netherlands and Belgium are among the top five worldwide of highest incidence in breast cancer, leading to an increase in post-mastectomy reconstruction interest.

This study aims to analyze readability of Dutch-written online patient-directed information on breast reconstruction.

An online patient query for the term “borstreconstructie” was simulated using the largest search engine, Google. Content from the 10 most popular web sites from the Netherlands and Belgium was collected and formatted into plain text.

Readability level assessment was performed using four available tools for the Dutch language: Accesibility.nl, Klinkende Taal, Texamen, and WizeNote, which measure readability according to the Common European Framework of Reference for Languages (CEFR).
