I have none of that, strangely. I did see my oncologist about it, then my surgeon came in to see me. I felt a lump that moved and I freaked out, but after examination he didn't have a concern that it would be anything sinister as I had clear margins of the breast and all lymph nodes that were removed and had all clear scans. It wasn't there in the beginning and only developed after surgery obviously. They mentioned cording because of the tight pull I feel in my arm and said seroma also. but I'm still freaking out over it
