Occupational Therapy in the Treatment of Breast Cancer-Related Lymphedema: A Narrative Review.

Background/Objectives: Breast Cancer-Related Lymphedema (BCRL) is one of the most prevalent complications among patients, causing physical limitations and a negative impact on their quality of life. Given its chronic nature and influence on personal autonomy, it is essential to review the therapeutic approaches applied to date. The main objective of this study was to analyze and to compare the effectiveness of the different treatments currently used in the management of BCRL, especially those that incorporate the intervention of an occupational therapist. Methods: A narrative review of the scientific literature published between 2013 and 2025 was conducted. The search was carried out in the PubMed, Scopus, Web of Science, and Dialnet databases. Inclusion and exclusion criteria were applied to select studies with therapeutic interventions, selecting eight studies for review. Results: Complex Decompression Therapy (CDT) is currently the standard treatment, although one of its components, manual lymphatic drainage, is controversial in terms of its effectiveness. Interventions such as Activity-Oriented Proprioceptive Anti-Edema Therapy (TAPA), adapted physical exercise, and hydrotherapy showed significant benefits in quality of life, functionality, and reduction in the volume of lymphedema. Conclusions: The therapeutic approach to BCRL must be multidisciplinary and personalized. Occupational Therapy (OT) provides a person-centered approach that contributes to improving occupational performance and patient well-being. More studies with greater methodological rigor and sample size are needed to unify clinical criteria.
