1. An abnormal shadow detecting system comprising:
- a mammary gland distribution map generating means which generates a mammary gland distribution map of each of left and right breasts by dividing an image of each of the left and right breasts into a plurality of ranges according to the densityof the image on the basis of image data representing the image,and an extracting means which extracts a bilaterally asymmetric range by comparing the ranges of the mammary gland distribution map for one of the left and right breasts with those of the mammary gland distribution map for the other breast.

Abstract
In an abnormal shadow detecting system, a mammary gland distribution map generating system generates a mammary gland distribution map of each of left and right breasts by dividing an image of each of the left and right breasts into a plurality of ranges according to the density of the image on the basis of image data representing the image, and an extracting system extracts a bilaterally asymmetric range by comparing the ranges of the mammary gland distribution map for one of the left and right breasts with those of the mammary gland distribution map for the other breast.

- 10. An abnormal shadow detecting system comprising a mammary gland distribution map generating means which generates a pair of mammary gland distribution maps of a breast by dividing each of two images of the breast taken at different times into a plurality of ranges according to the density of the image on the basis of image data representing the image, and an extracting means which extracts a difference range where a difference exists between the two images by comparing the ranges of the mammary gland distribution map for one of the images with those of the mammary gland distribution map for the other image.
