Lymphedema is an incurable chronic condition related to the impairment of the lymphatic system, in which localized swelling is present in the affected region(s) of the body. The blockage in the affected extremity leads to an increase in lymphatic fluid accumulation, resulting in the need for skilled intervention from a certified lymphedema therapist. Breast-cancer related lymphedema is a secondary condition characterized by its progression and chronic nature, often negatively affecting the quality of life of those diagnosed with it. The most common triggers include radiation treatment, chemotherapy treatment, or surgery. A combination of these treatments increases a patient’s risk of developing lymphedema. Despite lymphedema’s prevalence in women diagnosed with breast cancer-related lymphedema, the hardship it causes survivors, and the negative impact it has on body image, it is still a condition not widely discussed. The link between diet and lifestyle modifications continues to be researched through various studies and trials. Occupational therapists have a distinct role of informing, educating, and implementing evidence-based interventions for those affected by lymphedema, as well as educating other clinicians treating patients with this condition. This program development is designed to increase the knowledge and understanding of the role of occupational therapy in the treatment of lymphedema in its reversible and irreversible stages by means of diet modification to increase overall quality of life. The Occupational Therapy Practice Framework: Domain and Process will serve as the primary framework for this program.
