You know what already detects breast cancer? Mammograms followed by ultrasound.

We have screening programs for a reason. We know the sensitivity and specificity of these. They are widely available in any rich country that doesn’t treat its citizens like shit. There will absolutely be better stuff out there as we progress, with better sensitivity/specificity and lower harm (everything medical has some harm quotient) but I have a hard time wrapping my head around how they will best physics to provide better than state of the art today with this technology (and bow they will beat availability of current screening systems)
