OBJECTIVES To assess mammography utilization and knowledge, and to determine barriers associated with mammography utilization among Saudi women. Methods: We conducted a cross-sectional survey in 5 main geographic regions of Saudi Arabia from February 2015 to May 2015. The sample comprised women aged ≥40 years. Associations between socio-demographic factors and mammography use were tested using ...

In this paper a CAD (Computer Aided Diagnosis) system is proposed to optimize the feature set using hybrid of Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) technique called Genetical Swarm Optimization (GSO) in Digital Mammogram. Even though PSO is a good optimization technique, it may be trapped in local minima and may prematurely converge. So, the genetic operators are used in ...

Computer Aided Diagnosis (CAD) systems have improved diagnosis of abnormalities in mammogram images. The principal feature within the breast region is the breast contour. Extraction of the breast region and delineation of the breast contour allows the search for abnormalities to be limited to the region of the breast without undue influence from the background of the mammogram. After performing...

Women with diabetes have a higher breast cancer incidence and mortality. They are also significantly less likely to undergo screening mammography and present with more advanced stage than women without diabetes. The purpose of this study was to examine if women with diabetes are more likely to have delays in follow-up of abnormal mammograms, compared to women without diabetes. Using population-...

BACKGROUND Despite regular health care, preventive health issues may be neglected in patients with chronic diseases such as diabetes. Case-control studies in the United States have shown lower mammogram rates in women with diabetes; however, it is not known whether the presence of diabetes mellitus affects mammography use in a Canadian setting, where there is universal access to health care. ...

BACKGROUND In order to promote consumer-oriented informed medical decision-making regarding screening mammography, we created a decision model to predict the age dependence of the cancer detection rate, the recall rate and the secondary performance measures (positive predictive values, total intervention rate, and positive biopsy fraction) for a baseline mammogram. METHODS We constructed a de...

BACKGROUND Few studies have shown that the association between mammographic breast density and breast cancer persists for up to 10 years after the mammogram. We investigated associations of percent density, absolute dense, and nondense areas with breast cancer risk according to the time since the mammogram. METHODS This study included 1,028 incident breast cancer cases diagnosed within the Nu...

OBJECTIVE The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides free cancer screening to many low-income, underinsured women annually but does not routinely collect all data necessary for precise estimation of mammography rescreening rates among enrollees. MATERIALS AND METHODS To determine the percentages rescreened and to identify factors that encourage on-sched...
