The study looked at >2,000 studies.
Wonder how much they were paid to find the 10 studies that did not find a benefit?
30% of all bio-med papers appear to be fake, and 50% of those coming from China - May 2023

Effect of Vitamin D Supplementation on Risk of Breast Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Front Nutr . 2021 Apr 1;8:655727. doi: 10.3389/fnut.2021.655727
Ziyi Li 1, Liangzhi Wu 2, Junguo Zhang 1, Xin Huang 1, Lehana Thabane 3 4, Guowei Li 1 3Objective: Laboratory findings indicated that vitamin D might have a potent protective effect on breast cancer, but epidemiology studies reported conflicting results. The aim of the study was to conduct a systematic review and meta-analysis to clarify the efficacy of vitamin D supplementation on risk of breast cancer.
Methods: MEDLINE, EMBASE, The Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and abstracts of three major conferences were searched (up to December 8, 2020). Parallel randomized controlled trials (RCTs) examining the efficacy of vitamin D supplementation on risk of breast cancer or change of mammography compared with placebo in females were included. Data were meta-analyzed using a random-effects model. Bayesian meta-analysis was conducted to synthesize the results using data from observational studies as priors.
Results: Seven RCTs were identified for effect of vitamin D on risk of breast cancer, with 19,137 females included for meta-analysis. No statistically significant effect of vitamin D on risk of breast cancer was found in classical random-effects meta-analysis (risk ratio = 1.04, 95% confidence interval: 0.84-1.28, p = 0.71). When Bayesian meta-analyses were conducted, results remained non-significant. There was no statistically significant effect of vitamin D on mammography density observed: mean difference = 0.46, 95% confidence interval: -2.06 to 2.98, p = 0.72.
Conclusion: There is insufficient evidence to support the efficacy of vitamin D supplementation in breast cancer risk and change of mammography density. The protective effect of vitamin D on risk of breast cancer from previous observational studies may be overestimated. Systematic Review Registration: PROSPERO, identifier CRD42019138718.

25 Meta-analyses of Vitamin D and Breast Cancer
example: 2X reduction of deaths from Breast Cancer if have enough Vitamin D.- Appears that having lots of Vitamin D will reduce by 3 X the chance of Breast Cancer
wonder just how much more proof is needed- Breast Cancer 4X more likely if have poor genes
