I know it's easier said than done, Lisa, but try not to think too far ahead.
I've had more callbacks for additional films than I can count, so I know
from experience how hard it is. Just try to take one step at a time until
you know exactly what you're dealing with. That's much better than dealing with the "what ifs" because all the worry in the world won't change what is.
Most often the additional films show that it's nothing to be concerned about.
Monitoring may be all that's needed. As japdip said, if that's not the case, a biopsy may be needed. Even if that's the case, about 85% of biopsies turn out with benign findings, so the odds are in your favor.
Hang in there and I'm wishing you all the best,

The word "lobular" might raise suspicion a slight bit but then I think we always worry when something doesn't seem normal. After the additional views that have been ordered it may turn out to be nothing at all but when a determination can't be made then more films or actually more or different views must be taken to be certain. Even after the additional films if it isn't 100% clear as to what this area represents it may even require some type of biopsy. Everything needs to be investigated to a definite conclusion and this is what is being done in your situation. Please return with an update when you get your results. Regards ...
