Quizplus · Accepted Answer

Secondary lymphedema is typically caused by damage to the lymphatic system, such as trauma from surgery or radiation therapy. In this case, trauma to the lymph nodes from breast surgery would be the cause of secondary lymphedema. Hypoplasia (A) and congenital malformation (B) refer to conditions present at birth, and would more likely lead to primary lymphedema. Increased levels of lymphatic fluid (D) may be a symptom of lymphedema, but not necessarily the cause of secondary lymphedema.
