Objective: To evaluate association of sociodemographic, anthropometric, and epidemiological factors with result of mammogram in women undergoing breast cancer screening. Methods: This is a cross-sectional study with data obtained through interviews, anthropometric measurements, and mammography of 600 women aged 40 to 69 years at the Preventive Medicine Department of Hospital de Câncer de Barretos, Brazil, in 2014. The results of these examinations in the BI-RADS categories 1 and 2 were grouped and classified in this study as normal mammogram outcome, and those of BI-RADS categories 3, 4A, 4B, 4C, and 5 were grouped and classified as altered mammogram outcome...

PURPOSE: Although many studies have examined factors in predicting incomplete and delay in abnormal mammogram follow-up, few have used geospatial methods to examine these factors. Consequently, the purpose of this study was to examine the relationship between travel distance to health facilities and completion of abnormal mammogram follow-up among disadvantaged women in South Carolina. METHODS: Women participating in South Carolina's Best Chance Network between 1996 and 2009 with abnormal mammogram were included in the study...

BACKGROUND: In 2009, the US Preventive Services Task Force recommended that the decision to initiate screening mammography before age 50 years should be individualized. Herein, the authors examined whether health care providers are communicating regarding mammography decision making with women and whether communication is associated with screening behavior. METHODS: Data were drawn from the 2011 to 2014 Health Information National Trends Survey (HINTS). A total of 5915 female respondents aged ≥ 40 years who responded to the following question were included: "Has a doctor or other health professional ever told you that you could choose whether or not to have a mammogram?" We used logistic regression to generate odds ratios (ORs) and 95% confidence intervals (95% CIs) for predictors of provider communication and assessed whether provider communication was associated with mammography in the previous 2 years overall and stratified by age...

Breast screening is an important tool for the early detection of breast cancers. However, tumours are typically present in less than 1% of mammograms. This low prevalence could cause radiologists to detect fewer tumours than they otherwise would, an issue known as the prevalence effect. The aim of our study was to investigate a novel breast screening protocol, designed to decrease the number of tumours missed by radiologists, without increasing their workload. We ran two laboratory-based experiments to assess the degree to which the novel protocol, called the catch trial (CT) protocol, resulted in greater sensitivity (d') than the double screener protocol (DS), currently utilised in Australia...

BACKGROUND: Interval breast cancers are often diagnosed at a more advanced stage than screen-detected cancers. Our aim was to identify features in screening mammograms of the normal breast that would differentiate between future interval cancers and screen-detected cancers, and to understand how each feature affects tumor detectability. METHODS: From a population-based cohort of invasive breast cancer cases in Stockholm-Gotland, Sweden, diagnosed from 2001 to 2008, we analyzed the contralateral mammogram at the preceding negative screening of 394 interval cancer cases and 1009 screen-detected cancers...

INTRODUCTION: This work aims to explore radiation doses delivered in screening mammography in Australia, with a focus on whether compressed breast thickness should be used as a guide when determining patient derived diagnostic reference levels (DRLs). METHODS: Anonymized mammograms (52,405) were retrieved from a central database, and DICOM headers were extracted using third party software. Women with breast implants, breast thicknesses outside 20-110 mm and images with incomplete exposure or quality assurance (QA) data were excluded...

BACKGROUND: The effectiveness of breast cancer screening programs in reducing mortality is well established in the scientific literature. The National Breast Cancer Screening Program in Israel provides biennial mammograms for women of average risk aged 50-74 and annual mammograms for women aged 40-49 at higher risk. Compliance is high, but differential. This study explores different factors associated with breast cancer screening attendance among women aged 40-74 years. MATERIALS AND METHODS: Two main outcomes were studied: ever been screened and been screened in the 2 years preceding the study, using the cross-sectional Knowledge, Attitudes and Practices (KAP) Survey conducted in 2010-2012 among 2575 Israeli women aged 21+ years...

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-based health databases, this retrospective cohort study examined women between the ages of 50 and 74, with and without diabetes, living in the province of Ontario, Canada, who underwent screening through a centralized program and who had an abnormal mammogram between 2003 and 2012...

Cancer is the leading cause of death for Korean Americans (KAs). Breast cancer (BC) is the most commonly occurring cancer among KA women, and its rate has been rapidly increasing. Low BC screening rates for KAs puts them at greater risk for late-stage breast cancer. We conducted a systematic review of the published literature on cancer screening among KAs, and identified 38 eligible studies. Despite significant increases in mammogram utilization over the past two decades, KAs have consistently lower rates of mammogram screening than other American populations...

Breast MRI is being used more frequently for advanced screening for breast cancer. Patients may be at increased risk, or are symptomatic, with nonsuspicious mammograms. There is little data regarding the likelihood of a recommendation for biopsy, or for detecting a malignancy, in this population. We intended to determine the malignancy rate, number needed to treat, and positive predictive value for patients receiving adjunctive MRI at our institution. A retrospective review of all breast MRIs from 2008 to 2010 was done...

Minority and foreign-born women report lower rates of mammograms compared to non-Hispanic white, U.S.-born women, even though they have increased risk for developing breast cancer. We examine disparities in mammography across breast cancer risk groups and determine whether disparities are explained by socioeconomic factors. Propensity score methodology was used to classify individuals from the 2000, 2005, and 2010 National Health Interview Survey according to their risk for developing breast cancer. Logistic regression models were used to predict the likelihood of mammography...

BACKGROUND: A recent guideline by the American Cancer Society recommended that mammography (MMG) should be done for women starting in their mid-40s. In Thailand, information on opportunistic mammography screening is limited and data on the total incidence of breast cancer are also lacking. The purpose of this study was to estimate the breast cancer detection, incident and prevalence rates among Thai women. MATERIALS AND METHODS: We retrospectively reviewed the opportunistic mammography screening of normal women between 30 and 80 years who underwent the procedure between 2001 and 2010...

OBJECTIVE: Consuming low-value health care not only highlights inefficient resource use but also brings an important concern regarding the economics of disparities. We identify the relation of socioeconomic characteristics to the use of low-value cancer screenings in Medicare fee-for-service (FFS) settings, and quantify the amount subsidized from nonusers and taxpayers to users of these screenings. DATA SOURCES: 2007-2013 Medicare Current Beneficiary Survey, Medicare FFS claims, and the Area Health Resource Files...

Failures in repeat mammography decrease the potential benefits of screening; however, it is notable that the recent use of mammography is more frequently studied than repeat use. We estimated the prevalence and analyzed determinants for repeat mammography among women from Mexico, a developing country of Latin America. It was a two-stage study with an initial cross-sectional design (n = 1045) and a final case-control design that involved women of at least 45 years of age with no history of breast, ovarian, or uterine cancer...
