📋Overview
Lymphedema is a chronic condition characterized by swelling due to impaired lymphatic drainage, leading to accumulation of lymph fluid in tissues. It is classified as primary (congenital or hereditary lymphatic abnormalities) or secondary (caused by damage or obstruction of lymphatic vessels, often from surgery, infection, or radiation). The term 'lymphedema' is the modern preferred term and encompasses what was historically described under various legacy terms related to lymphatic swelling.
