Architectural distortion - waiting for biopsy

Hi, this is my first post here, and I'm in my early 40s.

I had a screening mammogram that showed a questionable architectural distortion, and had a diagnostic mammogram and ultrasound yesterday both of which confirmed the distortion. The radiologist told me that there are a limited number of things that can cause distortion, and my lack of previous surgeries on the breasts eliminates regular scars as one of the possible causes. I'm scheduled for a biopsy in two weeks. When I googled architectural distortions, I found studies and statistics that made me about the likelihood that architectural distortions that are seen on both mammogram and ultrasound would result in a breast cancer diagnosis - I saw some things that said the positive predictive value is 75-83%, but am hoping that I read that wrong or that the studies are of limited value.

I had a similar finding on the other breast last year, but two sets of biopsies on that breast did not show anything concerning - I think fibrocystic type changes. The radiologist suggested that I consider doing MRIs of both breasts even if this biopsy is benign, I think because he thought there would be some risk that the biopsy may not fully sample everything (that is why they ended up doing two biopsies last year) and even a benign finding may have some greater risk of becoming cancer over time. He said I could also do MRIs now before the biopsy, which I didn't want to do.

Wondering if other people have had similar findings and how things turned out.

Thanks!
