I can relate. After having a lumpectomy, two biopsies, an infection which caused additional tissue loss and radiation, there wasn't much tissue left on an initially small breast. I had a combination expander/implant placed. It had to be injected with saline and as the lumpectomy scar goes across the center of the breast and was tight, the liquid would fill above the breast as you mentioned. This made me quite self conscious because I knew there was this higher than normal mound on the one side. My girlfriend gave me a pair of fake breasts and I would place one over the remaining expanding breast tissue to help create symmetry when I wore clothing. It helped but there wasn't much I could do about the high mound, eventully the solution was adjusted and my cosmetic surgeon softened the scar across the breast to allow everything to take a more normal positioning. I'm very pleased with the final result. What we have to go through!
