Racial differences in mammographic breast density.
BACKGROUND African American women have a lower incidence but a higher mortality from breast carcinoma than Caucasians. A proposed explanation for this discrepancy is the decreased efficacy of screening among African American women. Increased breast density in African American women may result in decreased sensitivity of mammography. The purpose of this article is to determine whether there is a...
متن کاملMammographic breast density response to aromatase inhibition.
PURPOSE Mammographic breast density (MBD) is decreased by tamoxifen, but the effect of aromatase inhibitors is less clear. EXPERIMENTAL DESIGN We enrolled early-stage postmenopausal patients with breast cancer initiating adjuvant aromatase inhibitor therapy and ascertained mammograms before and at an average 10 months of aromatase inhibitor therapy. We matched cases to healthy postmenopausal ...
متن کاملEvaluation of glandular dose in mammography in the presence of breast cyst using Monte Carlo simulation
Introduction: Average glandular dose (AGD), entrance skin air kerma (ESAK) and normalized glandular dose (DgN) are the main dosimetric quantities in mammography. In this study, DgN is evaluated in the presence of breast cyst, which is a common disease among women and the influence of size, number and location of the cysts on the DgN is investigated. Materials and Meth...
متن کاملInvestigating the Factors Affecting the Mammographic Density of Breast Tissue in Patients Referred to the Breast Cancer Research Center, Iran
Introduction: Of the factors leading to false negative results in mammography is breast tissue density, and by increasing the density of breast tissue in mammography, the mammography sensitivity decreases. On the other hand, increasing the breast tissue density leads to increased risk of breast cancer. Various factors such as inheritance, genetics, hormonal and reproductive factors, and nutriti...
متن کاملMammographic breast density, endocrine therapies, and breast cancer risk
MBD and breast cancer risk Elevated MBD is considered one of the strongest risk factors for breast cancer regardless of whether it is assessed as a categorical or quantitative measure.6 Women in the highest categories of breast density have a 4to 6-fold increased breast cancer risk compared with women in the lowest categories. MBD has been shown to be a stronger risk factor for breast cancer th...
