Claim One:
1. A breast cancer detection system for detecting an architectural distortion of the mammary gland included in an X-ray image of the breast, comprising: a model calculating means that calculates a normal architecture model of the mammary gland that scatters in a fan shape from the nipple toward the greater pectoral muscle with respect to the X-ray image of the breast; an orientation extracting means that extracts orientations of linear components of an image texture of a region that form a shape of a shadow in the X-ray image of the breast; and a lesion determining means that compares the orientation of the mammary gland in the normal architecture model calculated by the model calculating means and the orientation extracted by the orientation extracting means with respect to a region of interest in the X-ray image of the breast including architectural distortion candidates of the mammary gland detected by preprocessing to calculate a feature quantity based on a difference between the orientations and determines whether the candidates are an architectural distortion of the mammary gland based on the feature quantity.
