Maternal breast cancer risk in relation to birthweight and gestation of her offspring.
(BMC, 2018-10-05)
BACKGROUND: Parity and age at first pregnancy are well-established risk factors for breast cancer, but the effects of other characteristics of pregnancies are uncertain and the literature is inconsistent. METHODS: In a ...
Reproductive profiles and risk of breast cancer subtypes: a multi-center case-only study.
(BMC, 2017-12-01)
BACKGROUND: Previous studies have shown that reproductive factors are differentially associated with breast cancer (BC) risk by subtypes. The aim of this study was to investigate associations between reproductive factors ...
Psychological stress, adverse life events and breast cancer incidence: a cohort investigation in 106,000 women in the United Kingdom.
(BIOMED CENTRAL LTD, 2016-07-15)
BACKGROUND: Women diagnosed with breast cancer frequently attribute their cancer to psychological stress, but scientific evidence is inconclusive. We investigated whether experienced frequency of stress and adverse life ...
Family history and risk of breast cancer: an analysis accounting for family structure.
(SPRINGER, 2017-08-01)
PURPOSE: Family history is an important risk factor for breast cancer incidence, but the parameters conventionally used to categorize it are based solely on numbers and/or ages of breast cancer cases in the family and take ...
Smoking and risk of breast cancer in the Generations Study cohort.
(BMC, 2017-11-22)
BACKGROUND: Plausible biological reasons exist regarding why smoking could affect breast cancer risk, but epidemiological evidence is inconsistent. METHODS: We used serial questionnaire information from the Generations ...
Genome-Wide Meta-Analyses of Breast, Ovarian, and Prostate Cancer Association Studies Identify Multiple New Susceptibility Loci Shared by at Least Two Cancer Types.
(AMER ASSOC CANCER RESEARCH, 2016-09-01)
UNLABELLED: Breast, ovarian, and prostate cancers are hormone-related and may have a shared genetic basis, but this has not been investigated systematically by genome-wide association (GWA) studies. Meta-analyses combining ...
Common variants in breast cancer risk loci predispose to distinct tumor subtypes.
(BMC, 2022-01-04)
BACKGROUND: Genome-wide association studies (GWAS) have identified multiple common breast cancer susceptibility variants. Many of these variants have differential associations by estrogen receptor (ER) status, but how these ...
Genome-wide interaction analysis of menopausal hormone therapy use and breast cancer risk among 62,370 women.
(NATURE PORTFOLIO, 2022-04-13)
Use of menopausal hormone therapy (MHT) is associated with increased risk for breast cancer. However, the relevant mechanisms and its interaction with genetic variants are not fully understood. We conducted a genome-wide ...
Etiology of hormone receptor positive breast cancer differs by levels of histologic grade and proliferation.
(WILEY, 2018-08-15)
Limited epidemiological evidence suggests that the etiology of hormone receptor positive (HR+) breast cancer may differ by levels of histologic grade and proliferation. We pooled risk factor and pathology data on 5,905 HR+ ...
Association of Body Mass Index and Age With Subsequent Breast Cancer Risk in Premenopausal Women.
(AMER MEDICAL ASSOC, 2018-11-01)
IMPORTANCE: The association between increasing body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) and risk of breast cancer is unique in cancer epidemiology in that a crossover ...
