Hormones and mammographic breast density

Maturitas, 2004
Mammographic density reveals information about the hormonal environment along with the heritability in which breast cancer develops. This is made possible by the widespread use of population screening by mammography. Increasingly this is an important observation not just for population studies, which reveal disease determinants, but also for the ...

Mammographic Density and Breast Cancer Characteristics

2014
The aim of this research is to investigate, in a screening population, the relationship between mammographic density and tumour characteristics including size, invasiveness and mammographic features. Mammograms of 105 women with screen detected breast cancer were analysed; 111 lesions were identified. Volumetric density measurements were obtained using

Variation in Mammographic Breast Density by Race

Annals of Epidemiology, 2001
Because of the observed racial differences in risk of developing breast cancer, the authors conducted a study to determine the variation in breast density, a strong predictor of breast cancer risk, by race and age.Study subjects were women enrolled in Group Health Cooperative of Puget Sound, Seattle, WA, aged 20-79 years, who had a screening mammogram ...

Mammographic breast density and characteristics of invasive breast cancer

Cancer Epidemiology, 2021
Inconclusive data exist on the association between breast density and breast cancer characteristics.We conducted a case-only study on 667 invasive breast cancers, using data from the Piedmont Cancer Registry. We applied a multivariate logistic regression model to estimate odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) of high ...

Education and mammographic breast density

Breast Cancer Research and Treatment
There are conflicting reports on the associations of education with mammographic breast density (MBD). To address this, we investigated the associations of education with MBD and additionally determined if and to what extent this association is mediated by known confounders such as age and adiposity.Women (n = 1155) were recruited during their annual ...

Mammographic density and breast cancer screening

Climacteric, 2020
Mammographic density, which is determined by the relative amounts of fibroglandular tissue and fat in the breast, varies between women. Mammographic density is associated with a range of factors, including age and body mass index. The description of mammographic density has been transformed by the digitalization of mammography, which has allowed ...

Mammographic Density and Risk of Breast Cancer

American Society of Clinical Oncology Educational Book, 2013
The radiographic appearance of the breast on mammography varies among women, and reflects variations in breast tissue composition and the different X-ray attenuation characteristics of these tissues. Fat is radiologically lucent and appears dark on a mammogram. Connective and epithelial tissues are radiologically dense and appear light.

Mammographic Breast Density Assessment

Applied Mechanics and Materials, 2013
In Taiwan, breast cancer has become the second leading type of cancerous diseases among women. The incidence and mortality rates keep rising, and mammography remains to be the only effective screening technique which is capable of detecting breast cancer at an early stage. High mammographic density is a strong risk factor for breast cancer. Based on BI-

Mammographic Density and the Risk and Detection of Breast Cancer

New England Journal of Medicine, 2007
Extensive mammographic density is associated with an increased risk of breast cancer and makes the detection of cancer by mammography difficult, but the influence of density on risk according to method of cancer detection is unknown.We carried out three nested case-control studies in screened populations with 1112 matched case-control pairs.
