A severe, traumatic injury to the lymph nodes also may damage the normal flow of lymphatic fluid. Frequently, lymphedema follows surgery and radiation treatment for cancer in the breast or groin area. Lymphedema usually begins with swelling of the hands or feet. Early detection and treatment often results in more successful treatment. When lymphedema remains untreated, the limb becomes more swollen and the skin hardens and loses elasticity.
Untreated lymphedema leads to infection and in some cases, irreversible complications.
As a result of recent lymphedema research, a dye injected into the skin can determine the status of the lymph nodes and detect where blockage is occurring. The dye test is safe and straightforward and is helpful in directing further therapies for the swollen extremity and eliminates unnecessary testing. With proper education and care, lymphedema can be avoided or kept under control. It's important that patients report any change in the size of their arms or legs to their doctors as soon as it is noticed. Lymphedema therapy is most effective when the condition is treated early by a healthcare professional certified in one or more of the recognized decongestive therapy techniques.
