Breast lump cytology results- C3 atypical

Hi, 

I recently had an ultrasound and mammogram after finding a small lump in right breast. Consultant also found 3-4 enlarged lymph nodes under left armpit. Radiographer aspirated both lump and lymph nodes by fine needle aspiration. Radiographer explained lump was a simple cyst.

I received my letter 4 days later which stated “a 2mm simple cyst in right breast with internal echoes- in keeping with chronic cyst” 

9 days later the breast nurse called to say lymph nodes were normal and reactive, however the lump has come back as C3 and a further biopsy will be needed. 

Has anyone had results  like this? 

Also found another larger hard lump in same breast in different area to lump that has already been aspirated.
