Vitamin D linked to breast cancer survival rates

A new study published in Carcinogenesis found vitamin D levels are linked to breast cancer survival rates.

The researchers found that out of 1,800 women, participants with vitamin D levels above 30ng/mL were about half as likely to die within 5 years of diagnosis compared to women with levels below 30ng/mL.

With every 10ng/mL increase, survival past 5 years increased by 20%. The results were still significant when the researchers adjusted for weight and age.

Also, women with higher vitamin D levels during the study were more likely to have smaller tumors.

The authors recognize that the study implies association, not a cause-effect relationship. Regardless, vitamin D is definitely something oncologists should pay attention to.
