Clinical Feasibility of Mobile App-Based Self-Management for Breast Cancer-Related Lymphedema

Clinical Feasibility of Mobile App-Based Self-Management for Breast Cancer-Related Lymphedema

The study evaluates a newly developed service that provides personalized self-management guidance based on evidence-based arm circumference measurements and resulting volume changes. The research aims to determine whether this digital solution is practical and acceptable for patients while identifying any unexpected challenges during implementation, ultimately establishing its potential for clinical integration into lymphedema care.
