What is Lymphedema?
Lymphedema occurs when the lymphatic system is damaged or blocked. This system is responsible for draining excess fluid from tissues. When disrupted, fluid accumulates, causing swelling and discomfort. Over time, this can lead to tissue fibrosis, making the condition harder to manage.
How Surgery Triggers Lymphedema
Breast cancer surgery, particularly procedures involving axillary node dissection, significantly increases the risk. Removing 10 or more lymph nodes raises the likelihood by 40%. Additionally, radiation therapy can cause scarring, further blocking lymphatic pathways. Symptoms may appear up to 24 months after treatment, making early detection crucial.
- Risk Factors: Axillary node dissection increases the risk fourfold compared to sentinel biopsy.
- Pathophysiology: Protein-rich fluid buildup leads to tissue changes.
- Timeline: Symptoms can emerge months or even years post-surgery.
