I97.2: Postmastectomy lymphoedema syndrome

Postmastectomy lymphedema syndrome is a medical condition that often arises after breast cancer surgery involving the removal of lymph nodes in the armpit area, also known as a mastectomy. Specifically, the syndrome is characterised by abnormal swelling, typically in the arms or hands, due to a blockage in the lymphatic system preventing proper drainage of lymphatic fluid. This blockage is typically caused by the disruption or removal of lymph nodes during the surgery. Common symptoms include a feeling of heaviness or fullness, decreased flexibility in the hand, wrist or elbow, and aching or discomfort in the affected limb. Without proper management, the condition can progressively worsen and potentially lead to infections or other complications. It is important to note that postmastectomy lymphedema syndrome can develop immediately post-surgery or even years afterward.
