Hi Grace, Queen-of-the-flaxseed-muffins! It probably is benign, but is there any chance your surgeon can refer you for an ultrasound-guided needle biopsy just to be sure? It's simple, pretty painless, fast, and good sonographers can find small things if they already know there's something to be found...I have had about 6 of them, and when they showed a negative result on some shadows on one of my former breasts

, it was a relief. Even when they were positive, it meant things swung into action really fast.
Sending you peace-of-mind vibes. Belindax
