Lymphedema after mastectomy occurs with a frequency as high as 30%. The incidence increases with more radical surgical dissection, as was often seen with radical mastectomies in the late 1800s. This is one aspect of breast surgery that has been greatly neglected. Surgery has often been deemed a success if the malignancy is eradicated. Patients may complain of symptoms as minor as arm heaviness to major ones such as massive chronic swelling, as was the case with our patient. The patient presented here had increasing lymphedema during a 14-year period after modified radical mastectomy and radiation therapy for advanced breast cancer. This condition had progressed to incapacitation of the extremity and a patient who as a result had become an invalid. The massively edematous extremity revealed no signs of recurrent disease or malignant degeneration. She underwent surgical intervention and physical therapy as procedures of choice to restore function.
