In April, 2009, it was reported on a digital mammogram that I had possible architectural distortion in the superior left breast. (Strong family history of breast cancer.) A few weeks later, I had a repeat mammo, spot compression views with CAD and ultrasound. Findings were heterogeneously dense breast tissue, architectural distortion persisting on true lateral view and spot compression. This area is not definitely seen on the CC or spot compression view. Sonographic evaluation demonstrated normal tissue planes with no solid or cystic mass. Six months later (Oct.,2009), all the above was performed again with no siginificant change, same as before. I am 67 yrs. old and prior to becoming post-menapausal, I always had fibrocystic breasts (very lumpy) but never a diagnosis of distortion. After menopause, the lumpiness was much reduced. All I know is that after each of these recent diagnostic tests, my left breast (the one in question) really hurts. Prior to all this testing, nothing at all. Could this be a sign of a cyst, an inflammed lymph node or just muscular soreness from the compression? I was uncomfortable for 3 months in May, now this Oct., I am again uncomfortable. My breast feels sore. Is this a bad sign?
