Does breast density measured through population-based screening independently increase breast cancer risk in Asian females?

Does breast density measured through population-based screening independently increase breast cancer risk in Asian females? Clin Epidemiol. 2018;10:61-70 Authors: Park B, Cho HM, Lee EH, Song S, Suh M, Choi KS, Kang BJ, Ko K, Yi A, Jung HK, Cha JH, Jun JK Abstract Purpose: The purpose of this study was to investigate the effects of breast density on breast cancer risk among women screened via a nationwide mammographic screening program. Patients and methods: We conducted a nested case-control study for a randomly selected population of 1,561 breast cancer patients and 6,002 matched controls from the National Cancer Screening Program. Breast density was measured and recorded by two independent radiologists using the Breast Imaging Reporting and Data System (BI-RADS). Associations between BI-RADS density and breast cancer risk were evaluated according to screening results, time elapsed since receiving non-recall results, age, and menopausal status after adjusting for possible covariates. Results: Breast cancer risk for women with extremely dense breasts was five times higher (adjusted odds ratio [aOR] =5.0; 95% confidence interval [CI]) =3.7-6.7) than that for women with an almost entirely fatty breast, although the risk differed between recalled women (aOR =3.3, 95% CI =2.3-3.6) and women with non-recalled results (aOR =12.1, 95% CI =6.3-23.3, P-heterogeneity =0.001). aORs for BI-RADS categories of breast density were similar when subjects who d...

This Practice Pearl describes an approach to screening mammography for average-risk women that encourages the use of shared decision-making that addresses benefits (early diagnosis and decreased mortality) and potential harms (false positives and overdiagnosis/overtreatment) in determining screening mammography initiation, frequency, and duration for women at average risk of breast cancer.

AbstractPurposeTo evaluate the frequency of missed cancers on breast MRI in women participating in a high-risk screening program.MethodsPatient files from women who participated in an increased risk mammography and MRI screening program (2003 –2014) were coupled to the Dutch National Cancer Registry. For each cancer detected, we determined whether an MRI scan was available (0–24 months before cancer detection), which was reported to be negative. These negative MRI scans were in consensus re-evaluated by two dedicated breast radiolog ists, with knowledge of the cancer location. Cancers were scored as invisi...

The objective of the present study was to assess the knowledge and practices relating to screening for breast cancer among women in Delhi. Methods: Data were obtained from 222 adult women using a pretested selfadministered questionnaire. Results: Rates for knowledge of known risk factors of breast cancer were: family history of breast cancer, 59.5%; smoking, 57.7%; old age, 56.3%; lack of physical exercise, 51.9%; lack of breastfeeding, 48.2%; late menopause, 37.4%; and early menarche, 34.7%. Women who were aged

CG Abstract OBJECTIVE: To investigate promoting factors for background parenchymal enhancement (BPE) in MR mammography (MRM). METHODS: 146 patients were retrospectively evaluated, including 91 high-risk patients (50 BRCA patients, 41 patients with elevated lifetime risk). 56 screening patients were matched to the high-risk cases on the basis of age. The correlation of BPE with factors such as fibroglandular tissue (FGT), age, menopausal status, breast cancer, high-risk precondition as well as motion were investigated using linear regression. RESULTS: BPE positively correlated with FGT (P

This study included 4130 cancer-free women within the Nurses ’ Health Study and Nurses’ Health Study II cohorts. Percent breast density (PD) was measured from digitized film mammograms using a computer-assisted thresholding technique and square root-transformed for the analysis. Average cumulative coffee/caffeine consumption was calculated using data from all food frequency questionnaires preceding the mammogram date. Information regarding breast cancer risk factors was obtained from questionnaires closest to the mammogram date. We used generalized linear regression to quantify associations of regular, decaffei...

CONCLUSIONS: In the examined group we observed a small percentage of women undergo Pap tests and mammography. Furthermore, medical recommendations regarding early detection of cancers are frequently ignored and disregarded by patients. PMID: 29284236 [PubMed - in process]

Abstract AIM: To compare background parenchymal enhancement (BPE) on contrast-enhanced (CE) spectral mammography (CESM) with CE magnetic resonance imaging (MRI), and evaluate how these relate to hormonal status, mammographic breast density (MBD) and MRI fibroglandular tissue volume (FGTV). METHODS AND MATERIALS: Between June 2012 to October 2015, participants in a cancer staging study underwent full-field digital mammography (FFDM), CEMRI, and CESM. Two readers independently rated FGTV, MBD, and BPE using the Breast Imaging-Reporting and Data System (BI-RADS) criteria. Inter-reader reliability was estimated u...

ConclusionsThe effect of pregnancies on mammographic density does not appear to become apparent before the age of menopause. The mechanism that drives the effect of pregnancies on mammographic density appears to be counter-regulated by other influences on mammographic density in younger patients.

Authors: Trieu, Mello-Thoms C, Peat JK, Do TD, Brennan PC Abstract Background: In recent decades the amount of new breast cancer cases in the southern region has been reported to increase more rapidly than in the northernVietnam. The aim of this study is to compare breast cancer risk factors between the two regions and establish if westernized influences have an impact on any reported differences. Method: Data was collected from the two largest oncology hospitals in the north and the south of Vietnam in 2015. Breast density, demographic, reproductive and lifestyle data of 127 cases and 269 controls were collected i...
