1. A method for breast cancer detection with an x-ray scanner, scanner, the method comprising: scanning a patient with the x-ray scanner, the scanning providing a frame of data representing breast tissue in the patient; classifying patches of the frame of data as of interest or not based on intensity; determining a probability of breast cancer for the patches that are of interest using a deep learnt regression at least partially trained on non-x-ray data, the probability not determined for the patches not of interest, the determining comprising inputting the patches that are of interest into the deep learnt regression, the deep regression outputting feature values; classifying the patches with the probability over a threshold using a machine-learnt classifier and not classifying the patches with the probability below the threshold; and displaying an indication of breast cancer for the patient based on an output of the classifying using the machine-learnt classifier.
