This is going to just increase false positives and unnecessary biopsies. This level of surveillance is not beneficial.
Edit: maybe for extremely high risk groups like it says in the article I guess, but the fact that they're explicitly testing it to detect noncancerous cysts (false positives) doesn't improve my confidence.
No one is going to get a biopsy after testing positive once. A positive test would mean you go to a doctor for a proper mammogram, THEN maybe a biopsy.
That's still an increased level of surveillance that is going against current recommendations. Unnecessary mammograms still result in unnecessary biopsies. You could use it for increased monitoring to detect growth I guess, but I doubt ultrasound is capable of that sort of resolution.
