To evaluate the readability of breast cancer treatment information published in WeChat public accounts (WPAs) and recommend how to compile highly readable treatment information. In April 2021, using the search term "breast cancer", we searched WPAs on the Sogou search engine and WeChat Mobile platforms and then selected up to four latest articles on breast cancer therapy from each. We applied linguistic analysis techniques to assess readability from text factors. The non-text factors used the Chinese version of the Suitability Assessment of Materials (SAM-C) instrument. Two researchers rated the articles independently. This study chose 136 articles from 37 WPAs. For text factors of readability, the mean Chinese language difficulty coefficient was 58.80 ± 8.70, indicating that the articles were challenging to read. For non-text factors, the mean SAM-C score was 52.12 ± 13.38, rated adequate. Among the dimensions, the layout and typography dimension scored the highest (74.63 ± 16.22), which was superior, followed by cultural appropriateness (58.64 ± 20.04), content (54.50 ± 21.77), learning stimulation and motivation (48.90 ± 23.24), and literacy demand (48.16 ± 17.58). The graphics dimension scored the lowest, with a score of 39.19 ± 17.60, and was deemed not suitable. The readability of breast cancer treatment information on WPAs is not highly rated and could be enhanced by text and non-text factors. The owners of WPAs should pay due attention to readability before releasing health information to ensure equal access and understanding of information by various users to achieve universal accessibility.

评估微信公众号（WPA）中发布的乳腺癌治疗信息的可读性，并建议如何编写高可读性的治疗信息。2021年4月，我们使用搜索词“乳腺癌”在搜狗搜索引擎和微信移动平台上搜索WPA，然后从中选出最多四篇有关乳腺癌治疗的最新文章。我们应用语言分析技术来评估文本因素的可读性。非文本因素使用中文版材料适用性评估（SAM-C）仪器。两名研究人员独立对这些文章进行评分。本研究从 37 个 WPA 中选择了 136 篇文章。文本可读性因素中，中文难度系数平均为58.80±8.70，表明文章阅读难度较大。对于非文本因素，平均 SAM-C 得分为 52.12 ± 13.38，评级为足够。维度中，布局和版式维度得分最高（74.63±16.22），表现优异，其次是文化适宜性（58.64±20.04）、内容（54.50±21.77）、学习刺激和动机（48.90±23.24）、识字需求（48.16 ± 17.58）。图形尺寸得分最低，得分为39.19±17.60，被认为不合适。WPA 上乳腺癌治疗信息的可读性评价不高，可以通过文本和非文本因素来增强。卫生公共机构所有者在发布健康信息前应充分注意可读性，确保不同用户平等获取和理解信息，实现全民无障碍。
