A recent study published in the journal Breast Cancer Research and Treatment found that vitamin D deficiency was associated with an increased risk of breast cancer among Asian women.
Cancer is defined as a disease caused by uncontrolled division of abnormal cells in a part of the body. Researchers have theorized that vitamin D plays a role in cancer through its ability to regulate cell growth.
Scientific literature has supported the beneficial role of vitamin D in cancer. Though, further research is needed to clarify the role of vitamin D in breast cancer. This relationship has not been explored among an Asian population.
Researchers recently conducted a large study with Korean women. They compared vitamin D levels between 3,634 breast cancer patients and 17,133 healthy controls.
The researchers found that vitamin D deficient women had 27% increased odds of having breast cancer than women with sufficient vitamin D levels. This association did not significantly vary by menopausal status.
The researchers concluded,
“Given the growing burden of breast cancer in Asia and dearth of studies examining the association between vitamin D and breast cancer risk in Asian women thus far, this study provides a meaningful evidence for potential preventive effect of vitamin D on breast cancer for this particular population.”
