BACKGROUND: In Italy women aged 50-69 are invited for a population-based breast cancer (BC) screening. Physicians, policy makers and patients associations agree on the need to inform women about the benefits and harms in order to permit an informed decision. Decision aids (DA) are an effective way to support people in their decisions about health. This trial aims to assess women's informed choices, according to their health literacy and values, on participating or not in BC screening for the first time...

BACKGROUND: The important but complicated research questions regarding the optimization of mammography screening for the detection of breast cancer are unable to be answered through any single trial or a simple meta-analysis of related trials. The Cancer Intervention and Surveillance Network (CISNET) breast groups provide answers using complex statistical models to simulate population dynamics. Among them, the MD Anderson Cancer Center (Model M) takes a unique approach by not making any assumptions on the natural history of breast cancer, such as the distribution of the indolent time before detection, but simulating only the observable part of a woman's disease and life...

OBJECTIVES: This study investigated whether certain mammographic appearances of breast cancer are missed when radiologists read at lower recall rates. METHODS: Five radiologists read one identical test set of 200 mammographic (180 normal cases and 20 abnormal cases) three times and were requested to adhere to three different recall rate conditions: free recall, 15% and 10%. The radiologists were asked to mark the locations of suspicious lesions and provide a confidence rating for each decision...

Renal cell carcinoma (RCC) is a highly prevalent disease worldwide with many cases being metastasised to various organs during the time of initial presentation. Metastatic RCC to the breast is a rare entity and can mimic primary breast carcinoma. In this article, we present a 63-year-old Caucasian woman presented with a breast mass that was detected by screening mammography and found to have a biopsy proven grade-II clear RCC in the breast tissue. Despite the high incidence and prevalence of primary breast cancer, metastasis from extramammary should be suspected in patients with a prior history of other cancers...

Widespread inconsistencies are commonly observed between physicians' ordinal classifications in screening tests results such as mammography. These discrepancies have motivated large-scale agreement studies where many raters contribute ratings. The primary goal of these studies is to identify factors related to physicians and patients' test results, which may lead to stronger consistency between raters' classifications. While ordered categorical scales are frequently used to classify screening test results, very few statistical approaches exist to model agreement between multiple raters...

An analysis of the adoption of secondary preventive behaviors is significant in regions with disparities in mammography use and breast cancer survival. Therefore, we determined the cognitive factors and the degree to which they differentiate stages of change in mammography among Mexican women. We also compared the decisional balance performance at Mexico, Switzerland, South Korea, and the USA. A cross-sectional study was designed for women in the stages of precontemplation (n = 240), contemplation (n = 243), action (n = 205), maintenance (n = 311), and relapse (n = 348)...

BACKGROUND: Breast cancer is a major health concern and remains the most common malignancy in women worldwide and in Turkey. Mammography, clinical breast examination (CBE), and breast self-examination (BSE) are recommended methods to detect early breast cancer in women. Many strategies have been developed to increase the rates of mammography, CBE, and BSE among Turkish women. Despite the benefits of breast cancer screening, these modalities are still underutilized by the majority of Turkish women...

Automatic segmentation of abnormal region is a crucial task in computer aided detection system using mammograms. In this work an automatic abnormality detection algorithm using mammographic images is proposed. In the preprocessing step, partial differential equation based variational level set method is employed for breast region extraction. The evolution of the level set method is done by applying mesh-free based radial basis function. The limitation of mesh-based approach is removed by using mesh-free based RBF method...

BACKGROUND: Delays in abnormal mammogram follow-up contribute to poor outcomes. In the current study, the authors examined differences in abnormal screening mammogram follow-up between non-Hispanic white (NHW) and Asian women. METHODS: The authors used a prospective cohort of NHW and Asian women with a Breast Imaging, Reporting and Data System (BI-RADS) abnormal result of category 0 or 3-plus in the San Francisco Mammography Registry between 2000 and 2010. Kaplan-Meier estimation for the median number of days to follow-up with a diagnostic radiologic test was performed, and the authors compared the percentage of women with follow-up at 30 days, 60 days, and 90 days and no follow-up at 1 year for Asian women overall (and Asian ethnic groups) and NHW women...
