PURPOSE: To assess the ability of chest CT to identify patients needing further evaluation of the breasts. METHODS: IRB approval was obtained with a waiver of consent. Women with chest CT and mammogram within 12months formed the cohort. A breast assessment and recommendation CT score (BARCS) analogous to mammographic BI-RADS was created and compared to the mammogram BI-RADS. RESULTS: BARCS and mammographic BI-RADS management recommendations were concordant for 77...

BACKGROUND: The Norwegian Breast Cancer Screening Program (NBCSP) was implemented across the country in 2005 and has been criticised for potential 'overdiagnosis', i.e. a breast cancer diagnosis that otherwise would not have been detected or treated in a woman's lifetime. We aimed to estimate overdiagnosis in the NBCSP based on the Norwegian Women and Cancer (NOWAC) study using both questionnaire information and record linkage information from NBCSP. METHOD: For 124,978 women aged 49-79 years from the NOWAC study, information on screened women could be cross-validated from the NBCSP database...

In order to automatically identify a set of effective mammographic image features and build an optimal breast cancer risk stratification model, this study aims to investigate advantages of applying a machine learning approach embedded with a locally preserving projection (LPP) based feature combination and regeneration algorithm to predict short-term breast cancer risk. A dataset involving negative mammograms acquired from 500 women was assembled. This dataset was divided into two age-matched classes of 250 high risk cases in which cancer was detected in the next subsequent mammography screening and 250 low risk cases, which remained negative...

Background: Invasive melanoma, a lethal form of skin cancer, is the seventh most common cancer in women. Factors such as a history of indoor tanning or sunburn and a personal or family history of skin cancer increase a woman's risk of developing a melanoma. Objective: Because the majority of melanomas occur in patients age 40 years or older, which is the age that is recommended for women to begin screening mammograms, the mammogram experience could be used to promote early detection of melanoma by introducing skin self-examinations (SSE) to a population of women who are already invested in preventive health...

This study aims to develop and test a new imaging marker-based short-term breast cancer risk prediction model. An age-matched dataset of 566 screening mammography cases was used. All "prior" images acquired in the two screening series were negative, while in the "current" screening images, 283 cases were positive for cancer and 283 cases remained negative. For each case, two bilateral cranio-caudal view mammograms acquired from the "prior" negative screenings were selected and processed by a computer-aided image processing scheme, which segmented the entire breast area into 9 strip-based local regions, extracted the element regions using difference of Gaussian filters, and computed both global- and local-based bilateral asymmetrical image features...

OBJECTIVE: Korean American (KA) women continue to have lower breast cancer screening rates than other racial groups. Perceived discrimination and trust have been associated with breast cancer screening adherence, but little is known about the associations in KA women. METHODS: Surveys were completed by 196 KA women in the Chicago metropolitan area. Multiple and Firth logistic regression analyses were performed to identify factors (perceived discrimination, trust, acculturation, cultural beliefs, health care access) influencing breast cancer screening adherence (mammogram)...

BACKGROUND: Breast cancer screening with magnetic resonance imaging (MRI) may be a useful adjunct to screening mammography in high-risk women, but MRI uptake may be increasing rapidly among low- and average-risk women for whom benefits are unestablished. Comparatively little is known about use of screening MRI in community practice. OBJECTIVE: To assess relative utilization of MRI among women who do and do not meet professional society guidelines for supplemental screening, and describe utilization according to breast cancer risk indications...

Breast density is one of the most significant factors that is associated with cancer risk. In this study, our purpose was to develop a supervised deep learning approach for automated estimation of percentage density (PD) on digital mammograms (DM). The input "for processing" DM was first log-transformed, enhanced by a multi-resolution preprocessing scheme, and subsampled to a pixel size of 800µm×800µm from 100µm×100µm. A deep convolutional neural network (DCNN) was trained to estimate a probability map of breast density (PMD) by using a domain adaptation resampling method...

Introduction: Screening mammography is used for detection of breast cancer and is interpreted using the Breast Image Reporting and Data System (BIRADS) convention. It is not routinely offered to women in countries which do not have a national screening programme resulting in a challenge for the radiologist who has to interpret these in the absence of previous mammograms. Aim: To analyse benign and probably benign lesions in screening mammograms in a hitherto unscreened population and suggest protocols to increase diagnostic confidence...

A 34-year-old healthy woman presented to the breast surgical oncology clinic with skin changes to her left nipple after being referred by her primary care provider. She attributed the skin changes to shearing from breastfeeding her third child 5 years earlier. Physical examination revealed an erythematous and friable nipple with loss of protrusion. The patient reported routine bleeding from her nipple, but said the skin changes had remained stable and denied any breast masses. The patient's last mammogram was 2...

Pilomatrix carcinoma is an exceedingly rare skin adnexal neoplasm derived from piliferous follicles, usually occurring in the head and neck region. Localization of this tumor in the breast is a rarity. We now report an unusual case of a 49-year-old female who presented with a palpable mass in the left breast for 2 years. Mammogram revealed a large, lobulated opacity with calcification, and positron emission tomography-computed tomography showed a metabolically active soft tissue mass measuring 15 cm involving all the quadrants of the left breast...

Context: Breast cancer is a biggest threat to women. X-ray mammography is the most effective method for early detection and screening of breast cancer. It is a tough challenge for the radiologist in reading mammography since it does not provide consistent result every time. Aim: To improve the primary sign of this disease, computer-aided diagnosis schemes have been developed. Using monitor, digital images of mammography are displayed and they can be lightened or darkened before they are printed on the film...

BACKGROUND: In mammography, breast compression is applied to reduce the thickness of the breast. While it is widely accepted that firm breast compression is needed to ensure acceptable image quality, guidelines remain vague about how much compression should be applied during mammogram acquisition. A quantitative parameter indicating the desirable amount of compression is not available. Consequently, little is known about the relationship between the amount of breast compression and breast cancer detectability...
