Re: Nodular Asymmetry
You do not say if this is the same facility you went to 18 months ago. If it is then this nodule was not present 18 months ago so they are check it out. By the sound of your report, I would think that because you have a family history of breast ca and they see something a little different, than they are going to investigate it. I would have thought that they would request some additional views to see if they can identify it better.
They are doing the u/s to see if it possibley is a cyst. If you have a copy of your report, check at the bottom of the report it shoud say BIRAD with a number 1,2,3,4. The number will usually tell you how concerned they really are.
BIRAD 2 or 3 means low probability, but needs follow-up.
My other thought is that they have scheduled your u/s "sometime in the future". I think if they were really concerned, than that u/s would be done alot sooner.
I hope this information helps.
