Background <p>Surgery is the most frequent treatment for breast cancer and requires postoperative follow-up to detect complications and monitor patient recovery. Postoperative telemonitoring has demonstrated benefits in improving rehabilitation and psychological well-being. However, patient expectations of and barriers to telehealth follow-up after oncologic breast surgery remain insufficiently explored.</p> Methods <p>A prospective survey was conducted among adult patients attending pre- or postoperative follow-up appointments for breast cancer in the Department of Breast and Reconstructive Surgery at the Civil Hospitals of Colmar between March and August 2025. The questionnaire comprised four sections: demographic data, treatments received, telemedicine accessibility and acceptability, and patient expectations of and barriers to telemonitoring.</p> Results <p>A total of 124 questionnaires were analyzed. Results demonstrated high accessibility to digital tools among participants. Although patients recognized several advantages of telemonitoring, most expressed a strong preference for in-person follow-up visits. The most expected features included the ability to report postoperative complications and to monitor recovery and pain. The main barrier was the fear of reduced human contact. Retired status was associated with lower acceptance of postoperative telemonitoring.</p> Conclusion <p>These findings support the implementation of a hybrid follow-up model combining early postoperative telemonitoring with later in-person consultations, which could help reassure patients and shorten hospital stays while maintaining personalized care. The monocentric design may limit the external validity of the findings. Future studies should explore patients’ perceptions following repeated use of telemonitoring tools and incorporate healthcare professionals’ perspectives on their integration into clinical practice.</p> Graphical abstract <p></p>
