White spots on mammogram

 Yesterday I had my first mammogram after treatment for dcis last year. On the image there was distinctive white spots on both breasts but in different areas. The radiographer went to get a colleague to check to make sure she had got enough coverage is what she said. They brought up my last year images & as I was craftily looking the white spots weren’t on last year’s. Trying to think positively and keep telling myself they are hormone changes but can’t wait for my results. Has anybody seen this on their mammograms?
