Combined effects of endogenous sex hormone levels and mammographic density on postmenopausal breast cancer risk: results from the Breakthrough Generations Study.
(NATURE PUBLISHING GROUP, 2014-04-02)
BACKGROUND: Mammographic density and sex hormone levels are strong risk factors for breast cancer, but it is unclear whether they represent the same aetiological entity or are independent risk factors. METHODS: Within the ...
Timing of pubertal stages and breast cancer risk: the Breakthrough Generations Study.
(BIOMED CENTRAL LTD, 2014-02-04)
INTRODUCTION: Breast development and hormonal changes at puberty might affect breast cancer risk, but epidemiological analyses have focussed largely on age at menarche and not at other pubertal stages. METHODS: We investigated ...
Identification of four novel susceptibility loci for oestrogen receptor negative breast cancer.
(NATURE PORTFOLIO, 2016-04-27)
Common variants in 94 loci have been associated with breast cancer including 15 loci with genome-wide significant associations (P<5 × 10(-8)) with oestrogen receptor (ER)-negative breast cancer and BRCA1-associated breast ...
Breast Cancer Risk After Recent Childbirth: A Pooled Analysis of 15 Prospective Studies.
(AMER COLL PHYSICIANS, 2018-12-11)
BACKGROUND: Parity is widely recognized as protective for breast cancer, but breast cancer risk may be increased shortly after childbirth. Whether this risk varies with breastfeeding, family history of breast cancer, or ...
The Risk of Ovarian Cancer Increases with an Increase in the Lifetime Number of Ovulatory Cycles: An Analysis from the Ovarian Cancer Cohort Consortium (OC3).
(AMER ASSOC CANCER RESEARCH, 2020-03-01)
Repeated exposure to the acute proinflammatory environment that follows ovulation at the ovarian surface and distal fallopian tube over a woman's reproductive years may increase ovarian cancer risk. To address this, analyses ...
Breast cancer risk in relation to history of preeclampsia and hyperemesis gravidarum: Prospective analysis in the Generations Study.
(WILEY, 2018-08-15)
Preeclampsia and hyperemesis gravidarum are pregnancy complications associated with altered sex hormone levels. Previous studies suggest preeclampsia may be associated with a decreased risk of subsequent breast cancer and ...
Genetically Predicted Body Mass Index and Breast Cancer Risk: Mendelian Randomization Analyses of Data from 145,000 Women of European Descent.
(PUBLIC LIBRARY SCIENCE, 2016-08-23)
BACKGROUND: Observational epidemiological studies have shown that high body mass index (BMI) is associated with a reduced risk of breast cancer in premenopausal women but an increased risk in postmenopausal women. It is ...
Night shift work and risk of breast cancer in women: the Generations Study cohort.
(NATURE PUBLISHING GROUP, 2019-07-16)
BACKGROUND: It is plausible that night shift work could affect breast cancer risk, possibly by melatonin suppression or circadian clock disruption, but epidemiological evidence is inconclusive. METHODS: Using serial ...
A case-only study to identify genetic modifiers of breast cancer risk for BRCA1/BRCA2 mutation carriers.
(NATURE PORTFOLIO, 2021-02-17)
Breast cancer (BC) risk for BRCA1 and BRCA2 mutation carriers varies by genetic and familial factors. About 50 common variants have been shown to modify BC risk for mutation carriers. All but three, were identified in ...
Risk of breast cancer in men in relation to weight change: A national case-control study in England and Wales.
(WILEY, 2022-06-01)
Breast cancer is uncommon in men and knowledge about its causation limited. Obesity is a risk factor but there has been no investigation of whether weight change is an independent risk factor, as it is in women. In a ...
