Relax...
....and I know those words are useless because I've had the same thing happen to me and I worried too.
Long story short it was simply a retake of the mamo to make sure what they think they saw wasn't anything to worry about. That said anything they may see on the retake is exactly why you go for a mamo in the first place! It's to catch something while it's small and treatable, you will be fine and getting your mamo done yearly (if you're in that catagory) is a great thing to do for your health.
BTW thanks for the reminder....I usually schedule mine around Mother's Day every year and it's that time again!
