I was due for my routine mammogram one month post-op so it was cancelled and my surgeon recommended 6 months post-op. I am dreading it! My mammograms hurt terribly prior to surgery, but I have a small lump that developed shortly after surgery right above my incision line, he wants that lump "marked" by the tech so the radiologist can look at it. Might be fat necrosis or a stitch, hopefully nothing serious.
