It would be easier for others to try to help you figure out if this is new and different if you'd posted this in the same thread as your previous information.
That said, I don't know that it matters whether this is in the same area or not. If it's in the same area, then it provides an explanation for the asymmetry, which is good. If the asymmetry is gone, that is good.
Complicated cysts are common and generally easy to identify on ultrasound imaging. They are similar to simple cysts in that they are fluid-filled (which shows up on ultrasounds but not on mammograms). Simple cysts are perfectly symmetrical, fully fluid-filled and evenly round or oval. Any cyst that doesn't perfectly match that description will be classified as a complicated cyst (unless it's a complex cyst, which can be quite different and may be more concerning). So complicated cysts may not be perfectly round or oval, or the borders might be slightly uneven, or they might contain little bits of solid debris.
As in your case, the standard assessment for a complicated cyst is a BI-RADS3, with the follow-up being repeat imaging in 6 months. The radiologist will be looking for either stability or shrinkage. I've had complicated cysts and never had any problems with them - eventually they shrunk and disappeared on their own. Your complicated cyst, at 2mm x 1mm x 2mm, is tiny tiny tiny.
