Low vitamin D linked to breast cancer

Add breast cancer to the conditions that may be tied to low levels of vitamin D. Several conditions have been associated with vitamin D levels, including multiple sclerosis, heart disease, depression and diabetes, Now, a new study from the University of California, San Diego School of Medicine found that premenopausal women with low levels of vitamin D in their blood were three times more likely to develop breast cancer than women with high levels of vitamin D.

The study looked at the vitamin D levels of 1,200 healthy women 90 days before a breast cancer diagnosis.

Though the results seem to link vitamin D deficiency with breast cancer, the study authors cautioned that these results were not conclusive enough to run out and start stocking up on vitamin D.  Instead, the doctors are using this study to investigate the possibility of a relevant window of time for cancer prevention in the last three months preceding tumor diagnosis -a time critical to the growth of the tumor.
