BACKGROUND: Several studies have shown that mammographic texture features are associated with breast cancer risk independent of the contribution of breast density. Thus, texture features may provide novel information for risk stratification. We examined the association of a set of established texture features with breast cancer risk by tumor type and estrogen receptor (ER) status, accounting for breast density. METHODS: This study combines five case-control studies including 1171 breast cancer cases and 1659 controls matched for age, date of mammogram, and study...

OBJECTIVES: This study compared persistent breast pain among women who received breast-conserving surgery for breast cancer and women without a history of breast cancer. METHODS: Breast cancer survivors (n=200) were recruited at their first postsurgical surveillance mammogram (6 to 15 mo postsurgery). Women without a breast cancer history (n=150) were recruited at the time of a routine screening mammogram. All women completed measures of breast pain, pain interference with daily activities and intimacy, worry about breast pain, anxiety symptoms, and depression symptoms...

PURPOSE: Develop a computer-aided detection (CAD) system for masses in digital breast tomosynthesis (DBT) volume using a deep convolutional neural network (DCNN) with transfer learning from mammograms. METHODS: A data set containing 2282 digitized film and digital mammograms and 324 DBT volumes were collected with IRB approval. The mass of interest on the images was marked by an experienced breast radiologist as reference standard. The data set was partitioned into a training set (2282 mammograms with 2461 masses and 230 DBT views with 228 masses) and an independent test set (94 DBT views with 89 masses)...

The breast is an unusual site for carcinoid metastasis. Due to increasing survival rates for carcinoid tumors, however, awareness of their rare complications is important. Carcinoid metastasis to the breast typically presents as a palpable breast mass or a mass on screening mammogram. Because imaging findings are nonspecific, the diagnosis is established through histological findings of neuroendocrine features corresponding with the known primary carcinoid pathology. Correctly distinguishing metastatic carcinoid from primary breast carcinoma is crucial to avoid more invasive procedures required for the latter...

The Friend to Friend plus Patient Navigation Program (FTF+PN) aims to build an effective, sustainable infrastructure to increase breast and cervical screening rates for underserved women in rural Texas. The objective of this paper is to identify factors that (1) distinguish participants who chose patient navigation (PN) services from those who did not (non-PN) and (2) were associated with receiving a mammogram or Papanicolaou (Pap) test. This prospective study analyzed data collected from 2689 FTF+PN participants aged 18-99 years from March 1, 2012 to February 28, 2015 who self-identified as African American (AA), Latina, and non-Hispanic white (NHW)...

Breast cancer risk is significantly reduced by improvements in lifestyle factors such as physical activity. Previous work suggests personal experiences such as false positive mammography or family history of breast cancer may influence these health behaviors. Surveys were distributed to women aged 40-75 who had received a negative mammogram from an academic hospital in Virginia in 2015. Measures assessed breast cancer worry and perceived risk, awareness of cancer risk factors, family history of breast cancer, false positive mammography experience, and readiness to change physical activity...

BACKGROUND AND OBJECTIVE: Early detection and diagnosis of breast cancer through mammography screening reduces breast cancer mortality by around 20%. However it is often a complex process to differentiate abnormalities due to the ill-defined margins and subtle appearances. METHOD: This paper investigates a new computer aided approach to detect the abnormalities in the digital mammograms using a Dual Stage Adaptive Thresholding (DuSAT). The suspicious mass region is identified using global histogram and local window thresholding method...

This study examined whether mammography receipt was associated with mortality due to causes other than breast cancer, hypothesizing that mammography screening was a proxy for the predisposition to seek preventive health behaviors. Using data on 89,574 women from the 2000 National Health Interview Survey and National Death Index, a discrete-time hazard model estimated the mortality from any cause except breast cancer as a function of screening status. Receiving a mammogram was associated with a 24% reduction in the likelihood of death all causes except breast cancer...

BACKGROUND: The objective of the study was to compare direct measurement with a conventional method for evaluation of clip placement in stereotactic vacuum-assisted breast biopsy (ST-VAB) and to evaluate the accuracy of clip placement using the direct method. METHODS: Accuracy of clip placement was assessed by measuring the distance from a residual calcification of a targeted calcification clustered to a clip on a mammogram after ST-VAB. Distances in the craniocaudal (CC) and mediolateral oblique (MLO) views were measured in 28 subjects with mammograms recorded twice or more after ST-VAB...

To compare the pathology and histologic grading of breast cancers detected with digital breast tomosynthesis to those found with conventional digital mammography. The institutional review board approved this study. A database search for all breast cancers diagnosed from June 2012 through December 2013 was performed. Imaging records for these cancers were reviewed and patients who had screening mammography with tomosynthesis as their initial examination were selected. Five dedicated breast imaging radiologists reviewed each of these screening mammograms to determine whether the cancer was visible on conventional digital mammography or whether tomosynthesis was needed to identify the cancer...

Delays in diagnosing breast cancer (BC) can lead to poorer outcomes. We investigated factors related to the diagnostic interval in a population-based cohort of 3202 women diagnosed with BC in Queensland, Australia. Interviews ascertained method of detection and dates of medical/procedural appointments, and clinical information was obtained from medical records. Time intervals were calculated from self-recognition of symptoms (symptom-detected) or mammogram (screen-detected) to diagnosis (diagnostic interval (DI))...

PURPOSE: Using image processing to extract nodular or linear shadows is a key technique of computer-aided diagnosis schemes. This study proposes a new method for extracting nodular and linear patterns of various sizes in medical images. METHODS: We have developed a morphology filter bank that creates multiresolution representations of an image. Analysis bank of this filter bank produces nodular and linear patterns at each resolution level. Synthesis bank can then be used to perfectly reconstruct the original image from these decomposed patterns...

We report the eighth case of eosinophilic mastitis and the first one without an association with peripheral eosinophilia or systemic involvement. A 51-year-old diabetic presented with a painful right breast lump. The mammogram, ultrasound, and magnetic resonance imaging suggested a diagnosis of periductal mastitis, however, a sinister etiology of breast carcinoma could not be ruled out. Diagnosis was made by vacuum assisted biopsy which revealed features of eosinophilic mastitis.

Inflammation is one of the hallmarks of carcinogenesis. High mammographic density has been associated with increased risk of breast cancer but the mechanisms behind are poorly understood. We evaluated whether breasts with different mammographic densities exhibited differences in the inflammatory microenvironment. Postmenopausal women attending the mammography-screening program were assessed having extreme dense, n = 20, or entirely fatty breasts (nondense), n = 19, on their regular mammograms. Thereafter, the women were invited for magnetic resonance imaging (MRI), microdialysis for the collection of extracellular molecules in situ and a core tissue biopsy for research purposes...
