Low Vitamin D Levels Linked to High Risk of Premenopausal Breast Cancer

A prospective study led by researchers from the University of California, San Diego School of Medicine has found that low serum vitamin D levels in the months preceding diagnosis may predict a high risk of premenopausal breast cancer.

The study of blood levels of 1,200 healthy women found that women whose serum vitamin D level was low during the three-month period just before diagnosis had approximately three times the risk of breast cancer as women in the highest vitamin D group.  The study is currently published online in advance of the print edition of the journal Cancer Causes and Control.
