Lymphedema resulting from breast cancer surgery is classified as?

1. Primary lymphedema

2. Idiopathic lymphedema

3. Secondary lymphedema

4. Dynamic lymphedema

The correct answer is: Secondary lymphedema

Lymphedema that arises as a result of breast cancer surgery is classified as secondary lymphedema. This condition occurs when the lymphatic system is damaged or obstructed due to external factors, such as surgical procedures, radiation therapy, trauma, or infections. In the case of breast cancer surgery, the removal of lymph nodes or damage to the lymphatic vessels during surgery can lead to fluid accumulation and swelling in the affected area, which characterizes secondary lymphedema. Primary lymphedema, on the other hand, is a genetic condition that occurs due to developmental anomalies in the lymphatic system, and idiopathic lymphedema refers to cases where the cause is unknown. Dynamic lymphedema is not a commonly recognized classification; lymphedema is typically categorized as primary or secondary, based on the underlying causes. Therefore, secondary lymphedema is the appropriate classification for lymphedema resulting from breast cancer surgery.
