Routine mammogram done last week came back with focal asymmetry in left breast. Spot compression is recommended. Going tomorrow for spot compressions. I have had 3 biopsies (all benign) and fibroadenoma removal (benign) on this breast. One of the biopsies was last year (same breast, left) for microcalcifications (benign). Had to go back for spot compression last year also, same breast, same finding. Should I be concerned?
