My doctor called & left a message for me at home (not my cell), which I didn't get until about 20 minutes ago (thanks again for calling, Kim!). In his message, he said that he's pretty sure it's a skin fold (how this would be possible, given the contortions and stretching, I have no idea), but since it's my baseline, he wants me to have more images done for the right breast. SO, he's unconcerned that it might "be something," but still needs me to go back in. I've already got the appointment scheduled for next Thursday. I'll just get it over with. That's all I want -- to have this all over with!
