The Lymph Flow Breast Shell is a silicone shell, made of 100% medical silicone, which is used under the bra and directly on the skin for support during lymphedema therapy for localized edema in the breasts. Small nubs on the inside of the shell provide a light massage which supports the loosening of the fibrotic tissue. The shell is washable and reusable. It is one size which can be cut to suit individual needs.
