Breast Cancer Risk From Modifiable and Nonmodifiable Risk Factors Among White Women in the United States

Objective  To evaluate combined risk stratification utility of common low penetrant single nucleotide polymorphisms (SNPs) and epidemiologic risk factors. Design, Setting, and Participants  Using a total of 17 171 cases and 19 862 controls sampled from the Breast and Prostate Cancer Cohort Consortium (BPC3) and 5879 women participating in the 2010 National Health Interview Survey, a model…

Breast cancer risk for the joint exposure to metals and metalloids in women: Results from the EPIC-Spain cohort

Environmental factors play a role in breast cancer development. While metals and metalloids (MMs) include some carcinogens, their association with breast cancer depends on the element studied. Most studies focus on individual MMs, but the combined effects of metal mixtures remain unclear. The aim of this study was to analyze the relationship between the joint…

Breast cancer incidence, by stage at diagnosis, and mortality in 21 European countries in the era of mammography screening: an international population-based study

Background Mammography screening programmes have been widely implemented across European countries over the past 40 years with the main aim to detect breast cancer earlier and thereby reduce breast cancer mortality. This study aimed to analyse and compare changes over time in breast cancer incidence, by stage at diagnosis, and breast cancer mortality across countries…

Breakfast Size and Prevalence of Metabolic Syndrome in the European Prospective Investigation into Cancer and Nutrition (EPIC) Spanish Cohort

Background: Recent evidence suggest that energy distribution during the daytimecould be a potential determinant for the development of metabolic syndrome (MetS). Objective: To cross-sectionally assess the association between breakfast size and the prevalence of MetS in Spanish adults. Methods: Our study included a subset of 3644 participants from the European Prospective Investigation into Cancer and…

BRCA1/2 testing for genetic susceptibility to cancer after 25 years: A scoping review and a primer on ethical implications

Background Mutations in the genes called BRCA1 and BRCA2 are associated with significantly elevated lifetime risk of developing breast and ovarian cancer. This year marks 25 years since genetic tests for BRCA1/2 mutations became available to the public. Currently, comprehensive guidelines exist regarding BRCA1/2 testing and preventive measures in mutation carriers. As such, BRCA1/2 testing…

Body Size at Different Ages and Risk of 6 Cancers: A Mendelian Randomization and Prospective Cohort Study

It is unclear if body weight in early life affects cancer risk independently of adult body weight. To investigate this question for 6 obesity-related cancers, we performed univariable and multivariable analyses using 1) Mendelian randomization (MR) analysis and 2) longitudinal analyses in prospective cohorts. Both the MR and longitudinal analyses indicated that larger early life…

Body shape phenotypes of multiple anthropometric traits and cancer risk: a multi-national cohort study

Background Classical anthropometric traits may fail to fully represent the relationship of weight, adiposity, and height with cancer risk. We investigated the associations of body shape phenotypes with the risk of overall and site-specific cancers. Methods We derived four distinct body shape phenotypes from principal component (PC) analysis on height, weight, body mass index (BMI),…

Body mass index and cancer risk among adults with and without cardiometabolic diseases: evidence from the EPIC and UK Biobank prospective cohort studies

Background Whether cancer risk associated with a higher body mass index (BMI), a surrogate measure of adiposity, differs among adults with and without cardiovascular diseases (CVD) and/or type 2 diabetes (T2D) is unclear. The primary aim of this study was to evaluate separate and joint associations of BMI and CVD/T2D with the risk of cancer.…

Body mass index and breast cancer risk among postmenopausal women with and without cardiometabolic diseases: Findings from two prospective cohort studies in Europe

Background Adiposity, measured by body mass index (BMI), is a known risk factor for postmenopausal breast cancer. However, whether the association of BMI with breast cancer risk differs among women with and without cardiovascular diseases (CVDs) or type 2 diabetes (T2D) is uncertain. Methods This study used individual participant data from the European Prospective Investigation…

Blood pressure and risk of cancer in the European Prospective Investigation into Cancer and Nutrition

Several studies have reported associations of hypertension with cancer, but not all results were conclusive. We examined the association of systolic (SBP) and diastolic (DBP) blood pressure with the development of incident cancer at all anatomical sites in the European Prospective Investigation into Cancer and Nutrition (EPIC). Hazard ratios (HR) (95% confidence intervals) were estimated…
