The WoMMeN project formed an interdisciplinary team in 2013 to explore using social media for breast cancer screening information and research. Through user-centered design and an online Facebook group, they collected feedback from 89 women on topics and formats. This informed the creation of the WoMMeN hub website and linked social media accounts. The hub launched in 2016 and provided peer support and health professional communication. Challenges included integrating patient and practitioner social media use. Ongoing work includes using digital marketing to reach underserved screening populations and further research.
