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 ...
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 ...
Genome-wide association study of anti-Müllerian hormone levels in pre-menopausal women of late reproductive age and relationship with genetic determinants of reproductive lifespan.
(OXFORD UNIV PRESS, 2019-04-15)
Anti-Müllerian hormone (AMH) is required for sexual differentiation in the fetus, and in adult females AMH is produced by growing ovarian follicles. Consequently, AMH levels are correlated with ovarian reserve, declining ...
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 ...
Domestic light at night and breast cancer risk: a prospective analysis of 105 000 UK women in the Generations Study.
(NATURE PUBLISHING GROUP, 2018-02-20)
BACKGROUND: Circadian disruption caused by exposure to light at night (LAN) has been proposed as a risk factor for breast cancer and a reason for secular increases in incidence. Studies to date have largely been ecological ...
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 ...
Comparative Validation of Breast Cancer Risk Prediction Models and Projections for Future Risk Stratification.
(OXFORD UNIV PRESS INC, 2020-03-01)
BACKGROUND: External validation of risk models is critical for risk-stratified breast cancer prevention. We used the Individualized Coherent Absolute Risk Estimation (iCARE) as a flexible tool for risk model development ...
Menopausal hormone therapy and breast cancer: what is the true size of the increased risk?
(NATURE PUBLISHING GROUP, 2016-08-23)
BACKGROUND: Menopausal hormone therapy (MHT) increases breast cancer risk; however, most cohort studies omit MHT use after enrolment and many infer menopausal age. METHODS: We used information from serial questionnaires ...
The Premenopausal Breast Cancer Collaboration: A Pooling Project of Studies Participating in the National Cancer Institute Cohort Consortium.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal ...
