A breast prosthesis is adapted to massage a patients chest so as to encourage circulation of interstitial lymph fluid. A breast form member has a front portion that has a shape corresponding to a human breast and a back portion. A protrusion member extends from the back portion. The protrusion member defines at least one protrusion extending outwardly therefrom. The protrusion is disposed so that when the breast prosthesis held against the patient at a preselected location, the protrusion will massage the preselected location, thereby encouraging circulation of interstitial lymph fluid.
