Breast cancer is the most frequent cancer type that is diagnosed in women. The exact causes of such cancer are still unknown. Early and precise detection of breast cancer using mammogram images or biopsy to provide the required medications can increase the healing percentage. There are much current research efforts to developed a computer aided diagnosis (CAD) system based on mammogram images for detecting and classification of breast masses. In this research, a CAD system is developed for automated segmentation and two-stages classification of breast masses. The first stage includes the classification of the masses into seven classes (normal, calcification, circumscribed, spiculated, ill-defined, architectural distortion, asymmetry), which is done using probabilistic neural network (PNN). The second classification stage is to define the severity of abnormality into two classes (Benign and Malignant) which were done using support vector machine (SVM). The results of applying the proposed method on two mammogram image show that the accuracy of detection and segmentation of the breast mass was 99.8% for mammographic image analysis society database (MIAS-DB) with 322 images and 97.5% for breast cancer digital repository (BCDR), BCDR-F03 and BCDR-DN01 with 936 images, while for the first classification stage has accuracy of 97.08%, sensitivity of 98.30% and specificity of 89.8%, and the second classification stage has an accuracy of 99.18%, sensitivity of 98.42% and specificity of 94.90%.

Comparison of the Diagnostic Accuracy of Next Generation Sequencing and Microarray Resequencing Methods for Detection of BRCA1 and BRCA2 Gene Mutations Bahsi, Taha; Ergun, Sezen Güntekin; Ergun, Mehmet Ali; Perçin, E. Ferda (Gazi University, 2018-4-1) Objective: Breast cancer constitutes 29 % of estimated new cases of cancer in women, and it is also one of the major cause of death in all cancer types. In this study, DNA samples of familial breast cancer patients with BRCA1 and BRCA2 mutations which had been analyzed using conventional DNA sequencing method, were also analyzed with new methods including microarray and next generation sequencing (NGS) in order to compare their results Methods: Seven patients with BRCA1 mutation, one patient with BRCA2 m...
Nuclear Deformability of Breast Cells Analyzed from Patients with Malignant and Benign Breast Diseases Antmen, Ezgi; Ermiş Şen, Menekşe; Kuren, Ozgur; Beksac, Kemal; Irkkan, Cigdem; HASIRCI, Vasıf Nejat (2023-03-13) Breast cancer is a heterogeneous and dynamic disease, in which cancer cells are highly responsive to alterations in the microenvironment. Today, conventional methods of detecting cancer give a rather static image of the condition of the disease, so dynamic properties such as invasiveness and metastasis are difficult to capture. In this study, conventional molecular-level evaluations of the patients with breast adenocarcinoma were combined with in vitro methods on micropatterned poly(methyl methacrylate) (PM...
Modeling of Breast and Gynecological Cancers Data and Investigating New Biological Findings Ağyüz, Umut; Purutçuoğlu Gazi, Vilda (null; 2018-06-27) The breast and gynecological cancers are two most common fatal cancers’ types in women in the world [1]. In oncological literature, these two cancers types are typically worked together since they are the risk factors of each other if the patient has one of these diseases [2]. In general, the cancers, like the heart diseases, are the systems’ ilnesses in the sense that any malfunctions in the associated transaction pathways cause problems in the activation flow, resulting in tumors. Therefore, the mathemati...
Medical electro-thermal imaging Carlak, Hamza Feza; Gençer, Nevzat Güneri; Department of Electrical and Electronics Engineering (2012) Breast cancer is the most crucial cancer type among all other cancer types. There are many imaging techniques used to screen breast carcinoma. These are mammography, ultrasound, computed tomography, magnetic resonance imaging, infrared imaging, positron emission tomography and electrical impedance tomography. However, there is no gold standard in breast carcinoma diagnosis. The object of this study is to create a hybrid system that uses thermal and electrical imaging methods together for breast cancer diagn...
Application of image enhancement algorithms to improve the visibility and classification of microcalcifications in mammograms Akbay, Cansu; Gençer, Nevzat Güneri; Gençer, Gülay; Department of Biomedical Engineering (2015) Breast cancer is the second leading cause of cancer deaths for women. Mammography is the most effective technology presently available for breast cancer screening, despite the fact that there are still some limitations of the imaging technique, such as insufficient resolution, low local contrast and noise combined with the subtle nature of the usual radiographic findings. One of the most important radiographic findings associated to the existence of breast cancer is the clustered microcalcifications. Especi...
