Artificial light at night and breast cancer risk: A systematic review and dose-response meta-analysis
نویسندگان
چکیده
BACKGROUND AND AIM: Artificial lightning has been suggested to be one of the environmental risk factor breast cancer onset and progression, based on epidemiologic evidence biological plausibility. Possible mechanisms include DNA damage, impairment melatonin estrogens secretion, inflammation, metabolic function. METHODS: We performed a systematic review epidemiological studies examining association between light-at-night (LAN) exposure we modeled shape relation using dose-response meta-analysis. After performing an online literature search up March 21, 2021, retrieved 16 eligible publications, including eight cohort case-control studies. RESULTS:In analyses comparing highest versus lowest LAN exposure, there was positive disease (risk ratio (RR)=1.10, 95% confidence interval (CI): 1.06-1.14), with relatively consistent associations observed in (RR=1.14, CI: 0.98-1.34) (RR=1.10, 1.06-1.14). In stratified analyses, RRs were similar for outdoor indoor while stronger RR among premenopausal women, women BMI category 20-25 kg/m2, estrogen-receptor cancer. The meta-analysis, implemented investigating only (for comparable assessment), indicated linear increasing 40 nW/cm2/sr after which plateau reached, especially women. CONCLUSIONS:Overall, this first assessing generally supports association. KEYWORDS: Light pollution, Cancer precursors, Environmental epidemiology, Non-chemical stressors

Subtypes of Benign Breast Disease as a Risk Factor for Breast Cancer: A Systematic Review and Meta-Analysis Protocol
AbstractBreast cancer is a multifactorial disease. Benign breast disease (BBD) is one of the most important risk factors for breast cancer. The etiology of BBD is unknown. It is divided into nonproliferative and proliferative diseases. The selection of studies will be based on titles, abstract screening, inclusion and exclusion criteria, and quality assessment. Previous studies have shown that ...

Background: Some studies have investigated the effects of iron on breast carcinogenesis and reported different findings about the association between Fe and breast cancer risk. This study was conducted to estimate this effect using meta-analysis method. Methods: A total of 20 articles published between 1984 and 2017 worldwide were selected through searching PubMed, Scopus, Embase, Web of Scien...
متن کاملNight work and breast cancer risk: a systematic review and meta-analysis.
The association between occupations that involve night shift work (a surrogate for exposure to light at night with subsequent melatonin suppression) and breast cancer risk is uncertain. We therefore conducted a systematic review and meta-analysis of observational studies to assess the effects of night work on breast cancer risk. Data sources were MEDLINE from January 1960 to January 2005, exper...
