Having been recalled after my last routine mammogram, I can understand your panicking, however much that sensible calm voice in your brain chips in. I had a look at the NHS website, which I suspect you did, which says while it is not a usual sign of cancer, it shouldn't be ignored. I was recalled because they needed to take a closer look of an area of one of my breasts, just to be sure. All was fine. If you are recalled, don't panic, as they don't take chances, which I find reassuring. If you are really worried, see you GP for reassurance. Let us know how you get on.
