Thank you everyone. The biopsy came back benign. Breast tissue with calcification. I am grateful!

I’m wondering about all these imaging and what it picks up. Mammo is X-rays, US is sound waves, MRI is magnetic.
I have a lesion in the same area that is the same size (1mm difference) found by US last October. My thinking is it’s the same lesion but my surgeon wants to me get a US follow up now. I was told the different imaging methods pick up different things. And it may not be the same lesion.
Is there an article that explains how each imaging method differs in detail?
Wishing everyone the best results!
