| most frequent cancer among women and the most common cause of cancer death. This study is a mammographic
screening study on 1000 women who came to a radiology center in Tabriz at 2010. The screening technique
included physical examination of breasts by an experienced physician before taking mammograms and then
mammography in two standard views.1000 women between ages 40-77 years old and without any clinical
symptoms was evaluated. Malignant mass or nodule: 13 cases, Benign mass or nodule: 34 cases, Benign calcified
nodule: 10 cases, Fatty breast: 6 cases and Ductal ectasia: 1 case. Association between malignancy signs in
mammography and positive clinical findings doesn’t have statistical significance (P=0.405) and association between
benign signs in mammography and clinical findings doesn’t also have statistical significance (P=0.692). varying in
prevalence of breast cancer in different studies suggests that many factors more than those we think about them as
same as: ages, family history, first pregnancy, menarche age, gravity, breast-feeding have rules in breast cancer
prevalence and these should will be studying in anthers analytic studies to know about these factors and ways to
decrease them and ultimately breast cancer mortality. |
