Breast cancer ranks first among all cancers worldwide, and is the leading cause of cancer-related death in women. It is therefore a major public health problem. The only means of preventing this scourge is screening mammography, which enables the diagnosis of infra-clinical breast lesions such as microcalcifications, which are related to a benign or malignant breast pathological process. The discovery of breast microcalcifications requires a precise, well-coded approach, ranging from the quality of the images to the action to be taken, i.e. Description of the microcalcifications, their BI-RADS classification and, finally, the action to be taken as a result.We hope that this book will be a useful resource for all those seeking to learn more about breast microcalcifications. We are convinced that this resource will help healthcare professionals to better understand breast microcalcifications and provide appropriate management.
