Lower Vitamin D level associated with larger breast cancer tumor size, greater likelihood of relapse

An international symposium on breast cancer at the end of 2011 featured a presentation from researchers who looked at the Vitamin D levels of women at the time they were diagnosed with breast cancer. The main finding: women with higher levels of D at diagnosis had significantly smaller tumors. Additional analysis of the follow-up data in this study showed that there was some relationship (termed of “borderline significance”) between higher levels of Vitamin D and lower risk of death from breast cancer. Furthermore, researchers detected a significant relationship between Vitamin D deficiency and risk of breast cancer relapse over a three year period.

The researchers suggested that Vitamin D’s anti-inflammatory effects might be the main mechanism by which Vitamin D levels influence breast cancer tumor size. The scientists presenting this research also called for further study to establish a clear cause-and-effect relationship between Vitamin D supplementation and breast cancer prevention. They also urged more research to determine the usefulness of Vitamin D supplementation as an additional therapy to bolster standard breast cancer treatments.
