A condition that is caused by damage to the lymphatic system’s capacity to move lymphatic fluid, often a result from having the axillary lymph nodes sampled or removed at the time of lumpectomy or mastectomy, or having had radiation to the axillary area. Symptoms include the hand, arm and tissues of the upper chest becoming swollen and painful. While it can be controlled with the use of compression sleeves and a massage technique called manual lymphatic drainage, it cannot be cured. Lymphedema can also occur in the feet and legs as a result of node removal in the groin or pelvic area.
