BACKGROUND: Past efforts to assess patient navigation on cancer screening utilization have focused on one-time uptake, which may not be sufficient in the long term. This is partially due to limited resources for in-person, longitudinal patient navigation. We examine the effectiveness of a low-intensity phone- and mail-based navigation on multiple screening episodes with a focus on screening uptake after receiving noncancerous results during a previous screening episode. METHODS: The is a secondary analysis of patients who participated in a randomized controlled patient navigation trial in Chicago...

Mammographic breast density has been established as an independent risk marker for developing breast cancer. Breast density assessment is a routine clinical need in breast cancer screening and current standard is using the Breast Imaging and Reporting Data System (BI-RADS) criteria including four qualitative categories (i.e., fatty, scattered density, heterogeneously dense, or extremely dense). In each mammogram examination, a breast is typically imaged with two different views, i.e., the mediolateral oblique (MLO) view and cranial caudal (CC) view...

OBJECTIVE: The objective of this study was to investigate the impact of decreasing breast compression during digital mammography and breast tomosynthesis (DBT) on perceived pain and image quality. MATERIALS AND METHODS: In this two-part study, two groups of women with prior mammograms were recruited. In part 1, subjects were positioned for craniocaudal (CC) and mediolateral oblique (MLO) views, and four levels of compression force were applied to evaluate changes in breast thickness, perceived pain, and relative tissue coverage...

OBJECTIVE: Breast cancer is the most common type of cancer in Canadian women and worldwide. Mammographic density is a well-established breast cancer risk. Recent evidence suggested inverse correlations among adiponectin, osteocalcin, and the risk developing breast cancer. The objective of the study was to evaluate the relationship between breast density and adiponectin and osteocalcin concentrations. METHODS: A cross-sectional study was performed in 239 women, age range 40 to 60...

An efficient health care requires both informed doctors and patients. Our current healthcare system falls short on both counts. Most doctors and patients do not understand the available medical evidence. To illustrate the extent of the problem in the setting of cancer screening: In a representative sample of some 5000 women in nine European countries, 92% overestimated the reduction of breast cancer mortality by mammography by a factor of 10-200, or did not know. For a similar sample of about 5000 men with respect to PSA screening, this number was 89%...

In breast cancer screening or diagnosis, it is usual to combine different images in order to locate a lesion as accurately as possible. These images are generated by using a single or several imaging techniques. As X-ray based mammography is used widespread, a breast lesion is located in the same plane of the image (mammogram), but tracking of a breast lesion across mammograms corresponding to different views is a daring task for medical physicians. According to this, simulation tools and methodologies that use patient-specific numerical models can facilitate the task of fusing information from different images...

We describe an automated methodology for the analysis of unregistered cranio-caudal (CC) and medio-lateral oblique (MLO) mammography views in order to estimate the patient's risk of developing breast cancer. The main innovation behind this methodology lies in the use of deep learning models for the problem of jointly classifying unregistered mammogram views and respective segmentation maps of breast lesions (i.e., masses and micro-calcifications). This is a holistic methodology that can classify a whole mammographic exam, containing the CC and MLO views and the segmentation maps, as opposed to the classification of individual lesions, which is the dominant approach in the field...

Some health research suggests that religious and spiritual variables positively predict health-screening behaviours. However, much of the literature on this topic has utilized exclusively religious samples, or has sampled from populations without uniform access to health care. Either of these issues may have artificially inflated the relationship between religion/spirituality and health-screening behaviours. The current study used data from the 2012 Canadian Community Health Survey to examine a general sample of women from New Brunswick and Manitoba (N > 1200)...

Epidemiological and animal studies suggest a protective role of green tea against breast cancer. However the underlying mechanism is not understood. We conducted a randomized, double-blinded, placebo-controlled phase II clinical trial to investigate whether supplementation with green tea extract (GTE) modifies mammographic density (MD), as a potential mechanism, involving 1,075 healthy postmenopausal women. Women assigned to the treatment arm consumed daily 4 decaffeinated GTE capsules containing 1315 mg total catechins including 843 mg epigallocatechin-3-gallate (EGCG) for 12 months...

BACKGROUND: The belief that early detection is the best protection against cancer underlies cancer screening. Emerging research now suggests harms associated with early detection may sometimes outweigh the benefits. Governments, cancer agencies, and organizations that publish screening guidelines have found it is difficult to "un-ring the bell" on the message that "early detection is your best protection" because of its widespread communication and enduring resonance. This study explores affective factors-and their interplay with relevant analytical factors-in public/laypersons' decision making about cancer screening...

BACKGROUND: Early detection of breast cancer using screening mammography provides an opportunity for treatment which can lead to significantly improved outcomes. Despite considerable efforts having been made, the rate at which Aboriginal and Torres Strait Islander (hereafter respectfully referred to as Aboriginal) women in Western Australia participate in BreastScreen WA's screening mammogram program remains below that for the overall female population of Western Australia. This study aimed to examine perspectives on breast screening amongst Aboriginal women in Western Australia...

BACKGROUND: Using the National Health Interview Survey (NHIS), we examine the effect of question wording on estimates of past year mammography among racially/ethnically diverse women ages 40-49 and 50-74 without a history of breast cancer. METHODS: Data from one-part ("Have you had a mammogram during the past 12 months?") and two-part ("Have you ever had a mammogram"; "When did you have your most recent mammogram?") mammography history questions administered in the 2008, 2011 and 2013 NHIS were analyzed...

In this paper we aim to produce a realistic 2D projection of the breast parenchymal distribution from a 3D breast magnetic resonance image (MRI). To evaluate the accuracy of our simulation, we compare our results with the local breast density (i.e. density map) obtained from the complementary fullfield digital mammogram. To achieve this goal, we have developed a fully automatic framework which registers MRI volumes to X-ray mammograms using a subject-specific biomechanical model of the breast. The optimization step modifies the position, orientation and elastic parameters of the breast model to perform the alignment between the images...

BACKGROUND: Mammographic percentage density is an established and important risk factor for breast cancer. In this paper, we investigate the role of the spatial organisation of (dense vs. fatty) regions of the breast defined from mammographic images in terms of breast cancer risk. METHODS: We present a novel approach that provides a thorough description of the spatial organisation of different types of tissue in the breast. Each mammogram is first segmented into four regions (fatty, semi-fatty, semi-dense and dense tissue)...

BACKGROUND: Calcification of breast arteries, observed on mammography, has been shown to have a positive association with cardiovascular disease and its risk factors, with literature suggesting that its presence should alert the clinician to underlying subclinical disease. METHOD: Of the women referred for mammograms between 1 January 2011 and 31 December 2011, 167 women over the age of 50 years, were included in the study. A retrospective review of the mammograms was done to determine the prevalence of breast arterial calcifications...
