While primary lymphedema is rare, numerous cancer patients develop secondary lymphedema, or the retention of lymphatic fluid. Lymphedema is characterized by progressive, irreversible fibroadipose tissue deposition. Non-surgical approaches such as compression therapy are the most common strategies to address lymphedema but are inadequate in the long term. Surgical procedures can reconstitute lymphatic drainage, but this approach is not curative. A new approach is needed to mitigate fibroadipose tissue deposition in lymphedema.
