Vitamin D has long been known as an essential nutrient that aids your bones with calcium absorption. A recent study shows that there may also be a link between vitamin D levels and surviving breast cancer.
Examining the Link between Vitamin D and Breast Cancer Survival
The study, performed by a research team from the Roswell Park Cancer Institute in Buffalo, began in 2006 with a group of women from California who had been diagnosed with invasive breast cancer. Participants were divided into three sub-groups based on blood levels of a particular vitamin D marker.
Women with more advanced cancers tended to have low levels of the marker. Over an average of seven years of follow-up, 100 of these women died compared to 76 women with high levels. There were approximately 1,600 women total involved in the study.
In addition, women with the highest vitamin D levels were 28 percent less likely to die of any cause, once factors such as tumor characteristics were accounted for. This link was the strongest among pre-menopausal women.
What Does This Mean for the Future?
According to lead author Song Yao, overall results showed “30 percent reduction of all-cause mortality” linked to vitamin D levels at the time of diagnosis. While the study supports previous research linking vitamin D with breast cancer survival, Yao said a randomized controlled trial would be needed to determine a direct cause-and-effect.
