In honor of breast cancer awareness, Have your vitamin D levels checked. Vitamin D3 should be taken with vitamin K2 to properly absorb. Several studies show that higher vitamin D levels are protective against many forms of cancer, particularly breast cancer. Women with vitamin D levels above 60 ng/mL have a much lower risk of breast cancer than those below 20 ng/mL.
Research has shown that once you reach a minimum serum vitamin D level of 40 nanograms per milliliter (ng/mL), your risk for cancer diminishes by 67 percent, compared to having a level of 20 ng/ml or less.4
Research shows most cancers occur in people with a vitamin D blood level between 10 and 40 ng/mL, and the optimal level for cancer protection has been identified as being between 60 and 80 ng/mL.
Vitamin D also increases your chances of surviving cancer if you do get it,5,6,7,8 and evidence suggests adding vitamin D to the conventional treatment for cancer can boost the effectiveness of the treatment.9
Several studies also show that higher vitamin D levels are protective against breast cancerspecifically. Importantly, a 2005 study10 showed women with vitamin D levels above 60 ng/mL have an 83 percent lower risk of breast cancer than those below 20 ng/mL, and I cannot think of any other strategy that can offer that kind of risk reduction. Mammograms certainly cannot.
More recently, a pooled analysis11 published in June 2018 of two randomized trials and a prospective cohort study came to a near-identical conclusion. The objective was to assess whether there are any benefits to having a vitamin D level above 40 ng/mL, as most studies do not venture into these higher levels.
Indeed, mirroring the 2005 findings, women with vitamin D levels at or above 60 ng/mL had an 82 percent lower incidence rate of breast cancer than those with levels of 20 ng/mL or less.
Pooled data were analyzed in three different ways. First, incidence rates were compared based on vitamin D levels ranging from 20 to 60 ng/mL. Next, statistical analysis using Kaplan-Meier plots were done. Third, multivariate Cox regression was used to examine the association between various vitamin D levels and breast cancer risk. According to the authors:
"Results were similar for the three analyses. First, comparing incidence rates, there was an 82 percent lower incidence rate of breast cancer for women with 25(OH)D concentrations ≥60 vs <20 ng/mL.
Second, Kaplan-Meier curves for concentrations of <20, 20–39, 40–59 and ≥60 ng/mL were significantly different, with the highest proportion breast cancer-free in the ≥60 ng/ml group (99.3 percent) and the lowest proportion breast cancer-free in the <20 ng/ml group (96.8 percent). The proportion with breast cancer was 78 percent lower for ≥60 vs <20 ng/mL.
Third, multivariate Cox regression revealed that women with 25(OH)D concentrations ≥60 ng/ml had an 80 percent lower risk of breast cancer than women with concentrations <20 ng/mL, adjusting for age, BMI, smoking status, calcium supplement intake, and study of origin …
Higher 25(OH)D concentrations were associated with a dose-response decrease in breast cancer risk with concentrations ≥60 ng/mL being most protective."
