Does lymphedema following breast cancer warrant clinical attention?

Secondary lymphedema (swelling) after breast cancer treatment usually develops on the hand, arm, shoulder, and/or breast on the treated side. It is commonly associated with the presence of other upper-body symptoms, such as pain and aching1; it impacts physical and psychosocial functioning and adversely influences quality of life.2 Moreover, it is considered incurable, progressive, and difficult to treat. Arguably, lymphedema is the most problematic and dreaded treatment-related complication of breast cancer.
