Many studies have found that women with higher vitamin D levels have a lower risk of developing breast cancer. But what about women who already have breast cancer? Could vitamin D help them?

In July 2018, results were published from a study assessing the relationship between vitamin D supplement use initiated after a breast cancer diagnosis and associated mortality among 5,417 women in Ireland aged 50 to 80 years old.

What were the findings of the study?

Supplement users were those who were taking more than 400 IU/day and were categorized as starting either within 6 months of diagnosis or more than 6 months after diagnosis. Overall, there was a 20% lower risk of death from breast cancer among those who started using vitamin D supplements after diagnosis compared to those who didn’t (P=0.048). If vitamin D supplementation was initiated within 6 months of diagnosis, there was a 49% lower risk (P<0.001).

These associations were adjusted for other risk factors such as age at diagnosis, smoking status, comorbidities, tumor stage, tumor grade, receptor status, chemotherapy, and medication use.
