1. A breast image processing method, adapted to a medical image processing apparatus, the breast image processing method comprising: obtaining at least one breast image by an image input module; detecting mammary glandular tissue in each of the at least one breast image through a mammary glandular tissue detector, wherein the mammary glandular tissue detector is based on texture characteristic analysis; calculating a mammary glandular tissue density in the at least one breast image; detecting at least one abnormal position in the at least one breast image by using a computer-aided detection (CADe) system; and comparing the at least one abnormal position with the mammary glandular tissue position in the at least one breast image by a false positive comparison module to determine whether the at least one abnormal position overlaps with the mammary glandular tissue position.
