Use of technology to facilitate a prospective surveillance program for breast cancer-related lymphedema at the Massachusetts General Hospital.

Breast cancer-related lymphedema (BCRL) is a negative sequela of breast cancer (BC) caused by trauma to the lymphatic system during surgery or radiation to the axillary lymph nodes. BCRL affects approximately one in five patients treated for BC, and patients are at a lifelong risk for BCRL after treatment. Early diagnosis of BCRL may prevent its progression and reduce negative effects on quality of life, necessitating comprehensive prospective screening.
