Had those new mammogram pics done this morning–and the long and short of it is, yeah, they think they were looking at scar tissue. I am to come back in six months for another followup just to keep an eye on it, and they also recommend a new baseline, post-reduction MRI just so that they have a new baseline for what it looks like in there.
So, yeah. Good to get that confirmed and I am deeply relieved. Or at least I will be when I get my energy back from being worn out from being nervous and tense!
Again, thanks all for your good wishes. Very much appreciated.
