I am scheduled for an ultrasound core biopsy for 9/8. They found what the radiologist thinks is a cyst due to a breast reduction that I had back in 2000. There were also 2 little calcifications that they will wait to repeat the mammo in 4-6 months. Here's the problem with that. In 2001, I had a mammogram that came back normal. I got the films and the report from back then (didn't bring that with me to the first mammo because it had come back normal). I reread that report and know that nothing was found. Could it be that there is a cyst there from the reduction? Also, when I have done research about cysts themselves, most places say that a cyst is often felt as a lump. I haven't had any lumps. I don't have any pain at all. Could it be something else? Help!
