Overview Breast Cancer and Vitamin D contains the following summary and sections
- 16+ 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
- Cancer - Breast category listing has

- Chemotherapy drugs often reduce Vitamin D levels, restoring levels helps– Aug 2018
- Chemotheraphy not work as well with low Vitamin D (colon cancer this time) – Aug 2018
- Breast Cancer Mortality reduced 60 percent if more than 60 ng of Vitamin D – meta-analysis June 2017
- Breast cancer reoccurred twice as often if have less than 20 ng of vitamin D – Dec 2018
- Diagnosed with breast cancer – take vitamin D to cut chance of death by half – July 2018
- Breast Cancer chemotherapy 2.7 X more likely to be successful if not vitamin D deficient – Dec 2017
- Palliative cancer benefit of 4,000 IU of Vitamin D – less opioids, infection, and CRP – Aug 2017
- Chemotherapy might be augmented with Vitamin D – Jan 2017
- Hypothesis: Chemo brain and other cognitive impairements are associated with low vitamin D
- Chemotherapy might be amplified by vitamin D has the following chart
The publication data on vitamin D3 in nearly all acute and chronic inflammatory diseases, metabolic syndrome and cancer [1,2] must lead to a consistent, year-round increase in the vitamin D levels to > 75 nmol/l (preventive) to 100-200 nmol/l (adjuvant-palliative). The vitamin D levels (25-OH) in the serum of the elderly and cancer patients often are dramatically low .
In primary and secondary prevention, there is a clear risk reduction with a lower incidence of breast cancer of 50-69% [4, 5, 6] or relapses with a reduction in mortality of up to 60% in a recent meta-analysis  in comparison of low to high Vit. D levels.
In addition, it obviously also has supportive significance: vitamin D3 levels can be reduced under chemotherapy, e.g. fall with anthracyclines, cyclophosphamide and taxanes, as these are pregnane X receptor ligands and so trigger an enzyme induction of 24-hydroxylase the increased degradation of 25 (OH) D and 1,25 (OH) D! Other substances used in oncology, such as dexamethasone, tamoxifen and aromatase inhibitors have the same negative effect for vitamin D levels .
According to small-scale studies, the active administration of vitamin D has a lowering effect on side effects such as stomatitis and taste disorders related to chemotherapy  or fatigue and arthralgia on aromatase inhibitors [10, 11] or jaw necrosis related to bisphosphonates .
In palliative pain therapy, an existing vitamin D deficiency leads to higher opioid dosages for pain control .
In practical consequence, every (breast) cancer patient should, depending on season, body weight u. a. factors, receive vitamin D3 between 1000 and 5000 IU daily to reach the target levels of 100-200 nmol/l.
