Mammographic Density and Breast cancer Death in the Breast cancer Surveillance consortium

چکیده
Methods We evaluated relationships between mammographic density and risk of death from breast cancer and all causes within the US Breast Cancer Surveillance Consortium. We studied 9232 women diagnosed with primary invasive breast carcinoma during 1996–2005, with a mean follow-up of 6.6 years. Mammographic density was assessed using the Breast Imaging Reporting and Data System (BI-RADS) density classification. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazards regression; women with scattered fibroglandular densities (BI-RADS 2) were the referent group. All statistical tests were two-sided.

Relationship between mammographic density and breast cancer death in the Breast Cancer Surveillance Consortium.
BACKGROUND Women with elevated mammographic density have an increased risk of developing breast cancer. However, among women diagnosed with breast cancer, it is unclear whether higher density portends reduced survival, independent of other factors. METHODS We evaluated relationships between mammographic density and risk of death from breast cancer and all causes within the US Breast Cancer Su...
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 کاملBarriers to Participation of Breast Cancer Patients’ Relatives in Mammographic Screening
Introduction: Breast cancer is the most common female cancer in the world and Iran and the leading cause of cancer death among Iranian women. One way to control this cancer is to get screened and diagnosed early. Given that screening in the general population is not possible, early detection of this cancer in high-risk women is one way to control it. Mammography is one way to diagnose breast ca...
متن کاملMammographic findings in different breast cancer subtypes (luminal, Her2 positive, triple negative)
Background: Prognosis and management of breast cancer are defined by different variables including histological type, grading, clinical stage, Her2+, estrogen and progesterone receptor conditions. Generally, mammography is one of the most important imaging which is done in breast cancer patients. The aim of this research was to evaluate different mammographic patterns in different breast cancer...
