Just to let you know. I also have something like this in one of my breasts. Got very scared last year on my monthly breast exam, had 2 mammo's, then an ultrasound on it, and even visited a surgeon, but it ended up being somehow one of the muscles in my breast is hardening. The surgeon didn't seem too worried about it since 'it moves with the breast'. I guess cancer doesn't move when the breast is manipulated? BUT I am VERY lumpy and have very dense breasts as well, so I'm watched pretty close as well. Good Luck and Congrats that it's benign!
I not only use all the brains that I have, but all that I can borrow.
