Lymphedema refers to swelling that generally occurs in one of your arms or legs. Sometimes both arms or both legs swell.
Lymphedema is most commonly caused by the removal of or damage to your lymph nodes as a part of cancer treatment. It results from a blockage in your lymphatic system, which is part of your immune system. The blockage prevents lymph fluid from draining well, and the fluid buildup leads to swelling.
There's no cure for lymphedema. But it can be managed with early diagnosis and diligent care of your affected limb.
