INTRODUCTION
BREAST cancer is currently the most common cancer affecting women worldwide [1]. In European women, it is the leading cause of cancer death, causing one in six of all deaths from cancers [2].In the U.S., a woman has a 12.15% (about one in eight) risk of developing breast cancer during her lifetime[3].
Mammography is one of the most reliable and effective methods for detecting breast cancer at it early stages [4]. In developed countries, population-based mammography screening programs have been implemented [1]. Women are encouraged to participatein regular breast examinations through mammography. In the U.S., annual mammographic screening is recommended for women at normal risk, beginning at age 40 [5]. In the U.K., women aged between …show more content…

First, for the approaches based on the shape/morphology of individual microcalcifications [7], [10], informative features cannot be attained when microcalcifications are very small (occupying only a few pixels) so that it seems meaningless to analyze the shape/morphological properties of such small objects. Second, microcalcifications may have very low contrast with respect to the surrounding tissue especially when microcalcifications form within dense tissue which has high and homogeneous intensity. As such, the lack of useful texture information within the background region affects the capability of the approaches based on the intensity variations and texture features [8], [27]. In addition, for the approaches describing the spatial distribution of microcalcifications within a cluster, the global
