I'm a little confused about what was said but I CAN tell you that when I've had mammograms that didn't show my cysts (which were aspirated and were fine) they did an ultrasound because I felt the "lump". The ultrasound found the lump. I was told that ultrasounds are better than mammograms! Don't know for certain, never checked it out further. I just felt better knowing that it did "find" my cyst and it wasn't just in my head.
