Lymphology Association of North America (LANA) Practice Exam

What could potentially trigger lymphedema in a patient with a history of breast cancer?

1. Skin infections or cellulitis

2. Regular exercise routines

3. Proper nutrition and hydration

4. Wearing compression garments

The correct answer is: Skin infections or cellulitis

Skin infections or cellulitis are recognized as potential triggers for lymphedema in patients with a history of breast cancer. This is primarily due to the fact that skin infections can compromise the integrity of the lymphatic system. When an infection occurs, inflammation may result, which can impair lymphatic drainage or exacerbate existing lymphatic dysfunction. In patients who have undergone surgical procedures, such as lymph node removal or radiation therapy associated with breast cancer treatment, the risk of lymphedema is significantly increased. Any additional strain on the lymphatic system, such as that caused by an infection, can lead to a higher likelihood of fluid accumulation in the tissues, thereby resulting in lymphedema. In contrast, regular exercise routines, proper nutrition and hydration, and wearing compression garments are generally beneficial and recommended for patients at risk of lymphedema. Regular exercise can promote lymph fluid circulation, proper nutrition and hydration support overall health and tissue function, and compression garments can help maintain lymphatic flow and reduce fluid buildup.
