Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Medicine - Department of Radio-diagnosis Summary: Tomosynthesis in this study showed better screening performance compared to mammography. The sensitivity of Tomosynthesis was 87%, the specificity was 97% , the positive predictive value of 87% , the negative predictive value was 97% and the diagnostic accuracy was 95%, while the sensitivity of mammography was 53%, the specificity was 85% , the positive predictive value was 50% ,the negative predictive value was 86%, and the diagnostic accuracy was 77% . Mammography is the best-studied breast cancer screening modality and the only recommended imaging tool for screening the general population of women. Deciding when and how to participate in screening should involve a personalized discussion between a woman and her provider, weighing the individual breast cancer risk factors and competing co-morbidities. In addition, a balanced discussion regarding both the benefits and risks of routine screening is warranted.FFDM is accused of having a low sensitivity because the overlapping breast tissue may hide an abnormality and this increases the number of false negative results. On the other hand it is accused of having a low specificity because the overlapping tissues may give the impression of a false abnormality which is responsible for a large number of false positive results
