The term “swollen arm” post axillary lymph node dissection is used to describe lymphedema of the upper limb that develops after surgical removal of axillary lymph nodes. This procedure is often performed as part of breast cancer treatment but may also be necessary for other medical conditions involving the axillary lymph nodes. A swollen arm is a common and unwanted consequence of this procedure because the removal of lymph nodes disrupts the normal flow of lymphatic fluid in the surrounding area, leading to fluid accumulation and arm swelling.

Causes of Swollen Arm Post Axillary Lymph Node Dissection 

The swollen arm occurs due to alterations in the lymphatic system during axillary lymph node dissection. During the surgery, axillary lymph nodes are surgically removed, which can damage or obstruct the lymphatic vessels that transport lymphatic fluid from the affected area. Without proper lymphatic drainage, lymphatic fluid accumulates in the arm, causing swelling and discomfort. 

Symptoms of Swollen Arm Post Axillary Lymph Node Dissection
