The multicomponent medication lymphomyosot improves the outcome of experimental lymphedema.

Background: Secondary lymphedema is a life-long disease of painful tissue swelling that often follows axillary lymph node dissection to treat breast cancer. It is hypothesized that poor lymphatic regeneration across the obstructive scar tissue during the wound healing process may predispose the tissue to swell at a later date. Treatment for lymphedema remains suboptimal and is in most cases palliative.

A chronic and latent lymphatic insufficiency follows recovery from acute lymphedema in the rat foreleg.

Secondary lymphedema in humans is a common consequence of axillary lymph node dissection (ALND) to treat breast cancer. Remarkably, secondary lymphedema generally first appears following a delay of over a year and can be triggered suddenly by an inflammatory insult. However, it remains unclear why the apparently functional lymphatic system is unable to accommodate an inflammatory trigger.
