BACKGROUND: Despite improvements in early detection of breast cancer, disparities persist in stage at diagnosis, which is an important prognostic factor. METHODS: We used the space-time scan statistic in SaTScan to identify geographic areas and time periods with significantly elevated proportions of female breast cancer diagnosed at the in situ or distant stage in New Jersey. The analyses were conducted with census tracts as the geographic unit of analysis, elliptical spatial windows, 3-year temporal windows, and Poisson models...

PURPOSE: To evaluate a method for measuring breast density using photon-counting spectral mammography. Breast density is an indicator of breast cancer risk and diagnostic accuracy in mammography, and can be used as input to personalized screening, treatment monitoring and dose estimation. METHODS: The measurement method employs the spectral difference in x-ray attenuation between adipose and fibro-glandular tissue, and does not rely on any a-priori information. The method was evaluated using phantom measurements on tissue-equivalent material (slabs and breast-shaped phantoms) and using clinical data from a screening population (n=1329)...

BACKGROUND: We analysed all female breast cancer (BC) cases in Tyrol/Austria regarding the shift in cancer characteristics, especially the shift in advanced BC, for the group exposed to screening as compared to the group unexposed to screening. METHODS: The analysis was based on all BC cases diagnosed in women aged 40-69 years, resident in Tyrol, and diagnosed between 2009 and 2013. The data were linked to the Tyrolean mammography screening programme database to classify BC cases as "exposed to screening" or "unexposed to screening"...

Communication campaigns often include components that have been designed for a specific population, a strategy referred to as targeting. Targeted narratives are story-based components of a campaign that feature a character or situation relevant to the intended audience. Though commonplace, few studies have explicated the underlying mechanisms by which targeted narratives exert influence. In a message evaluation study, 316 women aged 40-75 (Mage = 51.19, SD = 8.11) were exposed to one of two targeted narratives and asked to complete measures of model admiration, narrative memorability, and intentions to receive a mammography...

BACKGROUND: Mammography screening usually detects low-risk breast cancer in the western world. However, little is known about the ultrasound and mammography screen-detected T1 invasive non-palpable breast cancer (NPBC) in asymptomatic Chinese women. RESULTS: With the increase of tumor size (T1a, b, c), lymph node positivity (8.7%, 18.3%, 26.0%, p = 0.018), pN (p = 0.028) and TNM stage (p = 0.035) increased accordingly. Tumor size (T1a, b, c) was correlated with high Ki-67 index (defined as ≥ 14%, 37...

INTRODUCTION: Identifying high familial breast cancer (FBC) risk improves detection of yet unknown BRCA1/2-mutation carriers, for whom BC risk is both highly likely and potentially preventable. We assessed whether a new online self-test could identify women at high FBC risk in population-based BC screening without inducing anxiety or distress. METHODS: After their visit for screening mammography, women were invited by email to take an online self-test for identifying highly increased FBC risk-based on Dutch guidelines...

REVIEW
Lilian C Wang
Breast MR imaging is the most sensitive modality for breast cancer detection. This high sensitivity has led to widespread adoption of this technique, particularly in screening women at elevated risk for breast cancer. Despite its high sensitivity, standard breast MR imaging protocols are limited by moderate specificity and relative higher cost, longer examination time, longer interpretation time, and lower availability compared with mammography and ultrasound. As such, new techniques in MR imaging, including abbreviated breast MR imaging, pharmacokinetic modeling, and diffusion-weighted imaging, are active areas of research...

Breast density inform legislation is widely accepted in the United States and has fueled research regarding the clinical significance of dense breast tissue present on mammography and the value of supplemental screening. This article reviews the origins and current status of breast density inform laws and strategies for optimal breast density determination. Clinical evidence that dense breast tissue is associated with increased breast cancer risk is presented, together with a review of relative risk compared with other risk factors...

Synthesized mammography (SM) is a new imaging technique similar to digital mammography constructed from an acquired digital breast tomosynthesis (DBT) examination. SM allows for widespread screening using DBT, maintaining the benefits of DBT while decreasing the radiation of DBT by nearly half. This article reviews studies evaluating SM, most of which suggest that SM may be appropriate to use clinically to replace an actual acquired conventional 2-dimensional full-field digital mammogram (FFDM) when using DBT for breast cancer screening...

Digital breast tomosynthesis (DBT) is rapidly becoming the new standard of care for breast cancer screening. DBT has improved on the limitations of traditional digital mammography by increasing cancer detection and decreasing false-positive examinations. Interpretation of DBT is slightly different than digital mammography and therefore experience with the technology is paramount to achieve best performance. Examples of malignancies that should be recalled and benign findings that are safely called as benign are provided in this article...

Peter R Eby
The American College of Radiology, American Cancer Society, and US Preventive Services Task Force agree that mammography screening beginning at age 40 saves more lives than any other strategy. Despite these seemingly concordant summaries of the benefits of screening mammography, there are persistent debates regarding when to start and how often women should participate. Costs of screening, both monetary and personal, comprise the foundation of arguments against screening. This article specifically explores the evidence related to screening intervals and attempts to answer the question: should women be screened annually or biennially?...

A large body of evidence demonstrates a 30% to 50% mortality benefit of screening mammography for women aged 40 to 49. Because of more rapid cancer growth rates in younger women, annual screening is more effective than biennial. Studies indicate that selective screening of women aged 40 to 49 would miss the majority of breast cancers. If implemented, recent US Preventive Services Task Force breast cancer screening guidelines, which recommend against routine screening of women in their 40s, could result in thousands of preventable breast cancer deaths per year...

BACKGROUND: Mammography is one of the most popular tools for early detection of breast cancer. Contour of breast mass in mammography is very important information to distinguish benign and malignant mass. Contour of benign mass is smooth and round or oval, while malignant mass has irregular shape and spiculated contour. Several studies have shown that 1D signature translated from 2D contour can describe the contour features well. METHODS: In this paper, we propose a new method to translate 2D contour of breast mass in mammography into 1D signature...

Low preventive screening varies by region and contributes to poor outcomes for breast and cervical cancer. Previous comparative urban and rural research on preventive screening has focused on government programs. This study quantified and compared rural and urban preventive cancer screening rates for women who were privately insured. National Quality Forum measures were used to calculate rates for women within rural and urban parts of the same Hospital Referral Region (HRR) using claims data. Mammography screening rates for women age 24 to 69 years were 77...

Evaluation of mobile mammography for reducing social and geographic inequalities in breast cancer screening participation. We examined the responses to first invitations to undergo breast cancer screening from 2003 to 2012 in Orne, a French department. Half of the participants could choose between screening in a radiologist's office or a mobile mammography (MM) unit. We calculated the participation rate and individual participation model according to age group, deprivation quintile and distance. Among participants receiving an MM invitation, the preference was for MM...

Ductal carcinoma in situ (DCIS) of the breast represents a group of heterogeneous non-invasive lesions the incidence of which has risen dramatically since the advent of mammography screening. In this review we summarise current treatment trends and up-to-date results from clinical trials studying surgery and adjuvant therapy alternatives, including the recent consensus on excision margin width and its role in decision-making for post-excision radiotherapy. The main challenge in the clinical management of DCIS continues to be the tailoring of treatment to individual risk, in order to avoid the over-treatment of low-risk lesions or under-treatment of DCIS with higher risk of recurring or progressing into invasion...
