TL;DR: The study supports the use of official health statistics in the evaluation of randomized breast screening trials in Sweden by finding that 'breast cancer as underlying cause of death' according to Statistics Sweden resulted in relative risk estimates very similar to those based on the classification by the EPC.
Abstract: Between 1976 and 1982, four randomized mammography screening trials started in five screening centres in Sweden, involving 282 777 women (156 911 invited and 125 866 controls) with the aim to study if invitation to screening reduced the breast cancer mortality. An overview of the trials was performed to reduce the confidence intervals for the relative risk estimates. All 1 296 deaths occurring in women with breast cancer detected after randomization were evaluated by an independent endpoint committee (EPC), consisting of four physicians who reviewed collected medical information that was blinded regarding mammography screening. If there was disagreement between the EPC members at the initial individual evaluation the final classification was made at concensus meetings. In only 6.9% (n = 89) of the cases was there disagreement as to whether breast cancer was or was not the underlying cause of death. It was also found that ‘breast cancer as underlying cause of death' and ‘breast cancer as underlying or cont...

TL;DR: Conditional logistic regression analysis showed that breast asymmetry, height, family history of breast cancer, age at menarche, parenchyma type and menopausal status were significant independent predictors of Breast cancer.
Abstract: Introduction
It has been shown in our previous work that breast asymmetry is related to several of the known risk factors for breast cancer, and that patients with diagnosed breast cancer have more breast volume asymmetry, as measured from mammograms, than age-matched healthy women.

TL;DR: Because mammographically detected calcifications are frequently the only sign of breast cancer, the breast radiography equipment, screen-film imaging package, and film processing should be optimized to detect such calcifications.

TL;DR: In this article, magnetic resonance imaging (MRI) is the most useful imaging modality for the characterisation of breast implants because of its high spatial resolution and contrast between implants and soft tissues and absence of ionising radiation.
Abstract: The number of women with breast implants is increasing. Radiologists must be familiar with the normal and abnormal findings of common implants. Implant rupture is a well-known complication after surgery and is the main cause of implant removal. Although mammography and ultrasonography are the standard first steps in the diagnostic workup, magnetic resonance imaging (MRI) is the most useful imaging modality for the characterisation of breast implants because of its high spatial resolution and contrast between implants and soft tissues and absence of ionising radiation. MRI has the highest sensitivity and specificity for implant rupture, thanks to its sequences that can suppress or emphasise the signal from silicone. Regardless of the technique used, the overall aim of imaging breast implants is to provide essential information about tissue and prosthesis integrity, detect implant abnormalities and detect breast diseases unrelated to implants, such as breast cancer.

TL;DR: Investigation of mammographic and sonographic findings of metaplastic carcinoma of the breast found complex echogenicity with solid and cystic components may be seen sonographically and is related to necrosis and Cystic degeneration found histopathologically.
Abstract: OBJECTIVE. The purpose of this study was to investigate the mammographic and sonographic findings of metaplastic carcinoma of the breast and to correlate the radiologic features with clinical and histopathologic findings.CONCLUSION. Metaplastic carcinoma of the breast often manifests as a rapidly growing, palpable mass that has high density on mammography and may be microlobulated on sonography. Complex echogenicity with solid and cystic components may be seen sonographically and is related to necrosis and cystic degeneration found histopathologically. Although it is a rare breast malignancy and these features are not unique, metaplastic carcinoma should be included in the differential diagnosis for breast masses with these imaging features.
